GAMMADIST Excel Formula

Author Zaheer    Category Formulas     Tags ,

In the probability theory and stat, gamma distribution is two parameter family of continue probability distributions. This has scale parameter ? and the shape parameter k. When k is integer, then distribution represents Erlang distribution that is the sum of the K independent exponential distributed random variable, each of it has means of ? which is the equivalent to rate parameter of ?-1.

Gamma distribution is usually the probability model for waiting time, for example: life testing, waiting time till death is random variables that are usually modeled with gamma distribution. It’s the maximum entropy probability distributions for the random variate X for that E (X) = A is the fixed and greater than 0 and the E (ln (X) = ? (a) is fixed.

Gammadist Function Description

Excel Gammadist distribution returns Gamma Distribution, which’s usually used to provide probabilities for the values which could contain skewed distribution, like queuing analysis. The user can tell whether the probability density or the cumulative distribution function must be used.

Gammadist Function Syntax

GAMMADIST (x, alpha, beta, cumulative)

Where the arguments are:

  • x – refers to the value which you like to evaluate the function (should be ? 0)
  • Alpha – the parameter of distribution
  • Beta – parameter of distribution

Note: when the beta is equals to zero, and then it specifies the standard Gamma distribution

  • Cumulative – logical argument which tells the kind of gamma distribution to be computed. It can have values of true or false, which means:

True – compute the cumulative distributions function

False – compute probability density function

Excel is a very widely used tool in the day to day routine of individuals in performing their daily tasks. In the professional setup or domestic requirement, excel occupies a very important role which helps individuals in completing their tasks with consummate ease. The tool is so user friendly that it helps the user in performing actions in any manner that they can virtually conceive. This user friendly character of Excel has been the main reason why it has become a popular and widely used tool across the globe. All of this has been possible with the very well conceptualized Excel functions which make it very easy to use software tool.

There are different excel functions which can be effectively used to perform various functions while at work in a professional environment or a domestic setup. One of such functions is the Mode. Although it is a mathematical function, but not many individuals are familiar with the use of this process on their own and need some assistance to solve such mathematical situations. Often in such situations not everyone is able to work with such complex problems which make the use of excel the most appropriate software tool to make use off.

This Mode function returns its statistical mode (known as the frequently occurring value) together with a list of the supplied number. But if there are additional frequently occurring values for the supplied data then the function returns its lowest values.

The format used for this function is:

MODE(number1, [number2], [number3], …)

Wherein:

The number arguments are composed of an array of numeric values which you like to compute the mode. For Excel 2007 and 2010, you can provide up to 255 numeral arguments to its Mode function, however in Excel 2003, the mode function can just accept 30 numeral arguments. Any text or logical values in a supplied array are simply ignored by this function.

Arithmetically, Mode as a function measures the central tendency in a given equation or sequence of numbers, etc. Although there are other arithmetic functions as well which are used to measure the central tendencies like Average and Median, still Mode is the most commonly used function in the arithmetic use. Generally, such information is required in statistical research and these results are often required especially in a business environment to take knowledgeable decisions. The use of different excels functions like Mode function makes it easy for the users to work with complex mathematical numbers and achieve the desired results at the click of a button.

The combination of arithmetic function Mode as part of different excel functions make it very comprehensive and easy to use tool even for those individuals who are not very well versed and comfortable in working with mathematic calculations. The effectiveness of mathematical function like Mode is enhanced when it becomes a part of different excels functions because of the easiness and user friendly of the software.

Complex to complex calculations become very easy to perform and all one needs to know is how to plug in the correct formulas. Another advantage that these different excel functions provide is that anyone can link data in different sheets of a file or even separate files to perform mathematical calculations at a simple click of a button. Mode function can also be performed by linking more than two data files and the user can get results without worrying about its accuracy. Plugging in data in different excel files is very easy and it’s easier to link them in order to perform complex equations to achieve the desired results.

Author Zaheer    Category Formulas     Tags ,

One mathematical function that’s widely used for statistical purposes is known as NORMDIST. A very important tool, NORMDIST is often used in cases where hypothetical testing during statistical analysis is required to be done in order to perform complex mathematical tasks. NORMDIST works on the model of standard deviation and specified mean and calculates complex numerical data which is utilized for statistical research. Statistical research is often used in deriving certain decisions based on logical assumptions which are often obtained using the NORMDIST function of excel. On the hindsight, NORMDIST is a very complex process which cannot be used by everyone especially those who are not comfortable or familiar with its function and tools.

The NORMDIST parameters which is x, sigma and mu are the numeric values wherein the cumulative value is known as the coherent TRUE or FALSE value. The Sigma should be greater than zero, since there’s no comparable requirement for mu or x. For NORMDIST function, if the final argument is TRUE, NORMDIST returns its cumulative probability from the experimental value of one Normal random variable wherein its standard deviation sigma and mu is less than or equal to the value x. If the cumulative value is placed to FALSE then the NORMDIST function returns the elevation of bell-shaped curve of its probability density value.

At times, some individuals who are not very proficient in dealing with such situations, there is a need to acquire a helping tool which will assist them in solving the problem. For individuals who are not very familiar with the use of this process, there is help around the corner. With the advancement in technology several software have been developed which help individuals in getting over with complex and difficult numeric or mathematical problems. Different excel functions are very useful when it comes to solving such complex problems especially for individuals who are not very good of mathematical computations.

Excel as software is very useful and very dynamic. It has the ability to perform all the functions which the users can actually think of. The flexibility of the software assists those who can perform such task, which they can actually think off. What people needs to know is how to define the correct path or formulas and after that the entire calculations are done by the software with a single click of a button or one single data entry. All of these is possible with the kind of flexibility given by the different excel functions and provided by the software enabling it as one of the most user friendly software.

The usefulness and user friendly profile of the excel software comes from the different functions of this application which makes it as one of the most sought after software these days. The popularity of this software is not just in the professional environment but also on its domestic environment.

Microsoft Excel is an application that contains calculation, graph tools, and other mathematical and computation functions and formulas. One of the functions found in Excel is the Statistical Function which allows you to perform statistical computations, mean, median and mode, and other simple and complex statistical calculations. However, some of these functions are not present or pre-installed in the older versions of Excel.

One of the Statistical Function in Excel is the NORMINV Function that allows you to compute the contrary of the normal cumulative distribution. It also includes the given value of the mean and the standard deviation.

The syntax of the function or the sequence of arguments is NORMINV(odds,mean,average_dev). The argument probability refers to the normal distribution, the mean argument is the arithmetic mean value of the distribution, and the standard_dev argument refers to the standard deviation.

To test the function, open a black spreadsheet or worksheet and select a blank cell. Input the corresponding values of the mean with 5, average deviation of 2, and with the probability of 0.6. The function will be =NORMINV ( 0.6, 5, 2 ) and the result will be 5.506694206.

You can try another example with the use of source. Input in cell A1 the value 0.908789 which refers to the probability of the normal distribution. In cell A2 input the value 40 which is the value of the mathematics mean of the given distribution. Input in cell A3 the value 1.5 which is the value of the average deviation of the given distribution. The formula will now be inputted in cell A4 as =NORMINV (A2, A3, and A4) and the result will be 42.

The common errors that occur during the usage of this function are the #VALUE! error and the #NUM! error. The #VALUE! error occurs when the given arguments in the syntax are non-numerical values. For the #NUM! error when the given value of the probability is less than 0 or more than 1, If the standard_dev argument is less than or equivalent to 0.

If you would like to view the results from formula you can do this be selecting the cell and pressing Ctrl+` (grave accent). You can also do this by the hitting the Formulas tab and in the Formula Auditing select the Show Formulas

Microsoft Excel has been partly included in most of the computation activities in the office, school, or for personal businesses. This is because Excel offers a range of functions such as Text Functions, Statistical Functions, Engineering Functions, and many others.

In the Statistical Functions, you can do a lot of computations with it. This function allows the user to do complex and common statistical calculations such as the mode, median, mean, and, to probability tests. On the other hand, some of these functions are not pre-integrated or offered in earlier version of Microsoft Excel.

The sub-group distribution and test of probability includes Excel NORMSDIST function. The function enables you to easily compute Standard Normal Cumulative Distribution Function for a particular given value. This distribution function has a standard mean of zero and an average deviation of one wherein you can use the function to replace a table of the areas of the standard normal curves.

The syntax of the function NORMSDIST is =NORMSDIST (z). The arguments z in the function refers to the value which you would like to compute the function.

You need to open up a blank Excel spreadsheet or worksheet and try to input the sample values and function. Select the cell A1 and input the function =NORMSDIST (2.3) and the outcome of the function will be 0.98927589. Another example, select the cell A2 and input the formula =NORMSDIST (0) and the result will be 0.5. Lastly, input the formula =NORMSDIST (1.333333) and the result of the function will be 0.908789.

To change views from the result to formula and vice versa, select first the cell containing the formula and hit the keys Ctrl+` (grave accent). In addition, you can easily do this by selecting the cell, and then hitting on the required Formulas tab select the Formula Auditing group, and select the Show Formula button.

BAHTTEXT Excel Formula

Author Zaheer    Category Formulas     Tags ,

There are alloy of functions available or present in Microsoft Excel. One of its features is the capability to convert a specific number to a Thai text and also adds the Baht suffix on the word. Also, Microsoft Excel allows you to change the Baht format into a other styles available in the Regional Setting or in the Regional Option on the Control Panel. This feature is available on the Widows. Likewise, in Macintosh Excel the selections wherein you can change the format of the baht number to another style with the use of the Control Panel for Numbers.

The number is the one you would convert to a text. It could also be a cell that is a source which contains the number or numbers or the formula that is used to evaluate the number. Here is how you do it. First step is to create a blank worksheet or workbook and select an example on the Help topic and do not choose the headers on the column or row. After selecting an example, press on Ctrl+C. After, select the A1 cell on the worksheet and press Ctrl+V. Press CTRL+` or find the Formulas tab and select Formula Auditing group then select on the Show Formula button to be able to change from viewing the results to viewing the formulas which shows the results.

Bahttext function is under the lists of the Oddities section in Excel because it does not have the same task to convert the numbers to English. The term function here means a ready-made formula that has a value, does actions or operations, and returns a certain value. Function helps in simplifying and shortening certain or specific formulas in a worksheet. The function of the Bahttext syntax has the arguments or the the values which are information provided to do an action, technique, property, or action.

Also, Bahttext is the only feature of Excel which allows you to convert numbers to text. It is commonly requested in the Excel for the words to be converted into numbers. Bahttext or the conversion of number to Baht was made a function in Excel because it was said to be the most useful function in Numbertext. Also, the theory that there are more Excel programmers who enjoys eating Thai food and wanted to create a feature that will allow them to order food in Thai restaurants. Though this theory is not still proven nor denied.

CHAR Excel Formula

Author Zaheer    Category Formulas     Tags ,

Basic Description

Character Excel returns the character in relation to a given number (1 to 255), the character set used by the team.

Note that the set of characters may vary between different operating systems and therefore, the CHAR function may return different results on different computers.

Char function syntax is as follows: CHAR (number)

When the number is a number from 1 to 255, and can be supplied to the function, either directly or as a reference to a cell containing a number.

Examples of Functions of A:

Example 1

The Excel spreadsheet using the character to return the character associated with different numerical values ??provided. Please note that these results are from the ANSI character set

Example 2

A practical use of the char function is to insert line breaks in the text.

Note that in the above example to show the line break will need to ensure that wrapping the cell text is enabled. To do this:

  • Right-click the cell and choose Format Cells …
  • Select the “alignment” and check the Wrap Text option
  • Click OK

CHAR Function Error

If error occurs in the function of Excel Char, this is probably the # VALUE! Error Common mistake

# VALUE! – Occurs if the number supplied argument is not recognized as a numeric value or a number outside the range of 1 to 255.

Using the Excel Function of Char

Excel function character determines the character specified by the number of a character set. This is the character set for Macintosh computers and Macintosh ANSI character set for Windows computers. Char is often used to translate the character codes in the data that is imported from other computers. The following steps show how to use Excel function Char:

  • Learn the syntax of Char. It is Char (number) where number is the number of characters for those who want to know the character. Return the corresponding character set used on the computer.
  • Use any data type for the argument Char, provided that resolves to a numeric value. The CHAR function returns the value of #! error code if the argument is an integer between 1 and 255. From this restriction, we see that Char supports up to and including a set of characters of eight bits (2 ^ 8 = 256).
  • See the examples below to use Char: Char (65) = A, Char (66) = B, Char (67) = C and so on. These results mean that Excel is running on a Windows computer.
  • Explore other uses of the function code.

Char (CODE (“A”)) = A. Note this use to show that Char is the inverse function of code.
Code (256) = # VALUE! Although the argument is a number that is out of range, so it returns #! The error code

  • Study the ASCII character set to check the results of Char. Note that the values ??of 0 to 31 characters are printable and are represented by a small square in Windows

Char function syntax is:

= Char (number)

Number is the number used to retrieve the character.

RANDBETWEEN Excel function generates random numbers between a top and bottom number. In Excel 2007 is the default function of Excel. In Excel 2003, go to the Tools menu; click Add-ins, then add-on tools for analysis

Conclusion:

The CHAR function returns the character corresponding to a particular number. CHAR function is useful when you want to convert the number of pages in the numerical code of some files that you might have received from other teams

For example, you want to find the character in the series ’65 ‘, then the formula for the CHAR function should be written as

= CHAR (65)

The above formula when it returns the character ‘A’ which corresponds to the number 65.

You can also use cell references as an argument to the function CHARS. For example, you can use CHAR as CHAR (C5) to find the character corresponding to the current number in cell C5.

Therefore, it is how you can use the CHAR function to find the character corresponding to a number of applications in Excel 2010. This is how it works and how you can execute the function.

CLEAN Excel Formula

Author Zaheer    Category Formulas     Tags ,

Basic Description

The Excel function has a string of text provided and eliminates every non-printable character. The feature is designed to remove unprintable characters represented by numbers from 0 to 31 from 7-bit ASCII code, which often are in the beginning of the data was imported into Excel from other applications.

The function syntax is: CLEAN (text)

When the argument of “text” can be supplied to the function, either directly as a string returned from another formula, or a reference to a cell that contains text

Examples CLEAN Function

The following example shows the function of Excel Clean used in four different strings of text. In Excel, the clean function eliminates each non-printable character from a string.

The function syntax CLEANING: CLEAN (text)

The text is the value of every single non-printable characters removed.

This applies to:

  •  Excel 2007, Excel 2003, Excel XP, Excel 2000

How to Use the Cleaning Function in Excel?

Excel CLEAN function eradicates the entire non-printable characters from a string. Often used for importing text from other applications those are not compatible with your OS. The following steps show how to use Excel’s CLEAN function

Learn the syntax of Clean. CLEAN (raw_text) where raw_text is not printable character string to be deleted.

Understand the purpose of the CLEAN function. It is originally designed to eliminate the first 32 characters of ASCII text, since these values ??can not be printed. However, the values ??127, 129, 141, 143, 144 and 157 in the Unicode character set without printing too, but not removed for cleaning. Look at a simple example of the CLEAN function. Type = CHAR (6) and “proof text” CHAR (6) in cell A1 and type = Clean (A1) in cell A2. The result in cell A2 is “proof text.” Note the use of CHAR to insert non-printable characters in the sample text and its subsequent withdrawal by Clean.

Study more complex use of the CLEAN function. Combine with Clean to replace all unprintable characters of text. This includes the Unicode character set in step 2, which can cause problems in filtering, searching and sorting.
Use substitute six times first to replace each of the six high-value doe’s not print Unicode characters with one of the first 32 ASCII characters. For example, the first use is as follows: Substitute (raw_text, CHAR (127), CHAR (7)). Then run a cleaning to take out every single non-printable character.

Cleaner is a lightweight graphical complement to Microsoft Excel which can improve the Excel charts in many ways. These various issues as we know the labels have difficult to read, the problems of the size scale of the source, and issues of contrasting color.

Letters clean install by running the graphics clean install.Xls after unpacking the contents of the download to local directory. Excel users to ensure that macros are activated which can be done with one click in Excel 2010. Users of earlier versions of Excel go to Tools> Macro> Security and select medium security.
The template displays the options to install a cleaning card as a complement to uninstall a previously installed version of the supplement or trying to clean up the graphics on the active worksheet

Clean graphics options, a window that is activated each time from within Excel. All options are selected automatically cleaning the option of removing those who do not need or want.

  •  Set the font size
  •  Set the axis labels and scale
  •  3D Secure
  •  Definition of colors
  •  InsuranceMesawaste

The result is a cleaner and professional looking graphics. The Excel add-in is added to the Format menu or the Add-Ins menu, using Excel 2010. Provide options to remove all the cards which are open or just specific graphic displayed on the screen.

Clean graphics can be unprofessional looking Excel charts professionals. Batch mode, allowing the conversion of cards at once, says the conversion will not have to be a tedious process.

The Excel add sometimes has difficulty processing complex graphics. It’s a good idea to have a backup copy of a document prepared in case that despite the setback should be sufficient to return to the previous graph, if something went wrong.

Graphic clean is compatible with Excel 2010, 2007 and 2003. It can be downloaded from the website of the developer. The Excel add-on displays an error message when installed in Excel 2010.

PEARSON Excel Formula

Author Zaheer    Category Formulas     Tags ,

There’s a lot of functions that you can use in MS Excel. These functions allow you to do graphs, compute values, and many others. Excel is composed of Engineering Functions, Math Functions, Statistical Function and others which you are use to easily manage data.

The functions in Excel are divided into sub-groups which will allow you to easily find the function you need and perform it. Excel has Statistical Functions which includes the Distribution and Tests of Probability. Included in this sub-group is PEARSON function which basically allows you to calculate Pearson Product-Moments Correlation Coefficients for 2 groups of value.

The syntax of PEARSON functions include:

=PEARSON (array1, array2)

…whereas array1 argument refers to the group of independent values and the array2 argument is a group of dependent values. The given arrays arguments can be in the form of cell that contains the values and names or numbers. If the given cells in the syntax contains tests, logical cells, or when the cell is empty then it will not be included. If the cell in the argument contains the numerical value zero then it will still be included. The error #N/A will occur if the cells are empty and if it does not have the same data point.

In blank Excel worksheet or spreadsheet input the independent values 9 in cell A1, 7 in cell A2, 5 in cell A3, 3 in cell A4, and 1 in cell A5. Likewise, input the independent values 10 in cells B1, 6 in cell B2, 1 in cell B3, 5 in cell B4, and 3 in cell B5. Now input the formula =PEARSON (A1:A5, B1, B5) and the result will be 0.699379. The result is described as Pearson products moment correlation coefficients of the given data in cells.

The #N/A error occurs in PEARSON function if the given arrays or source cells which contains the values differ in lengths or number of cells. The #DIV/0! Error happens if the given arrays or source cells does not contain any data and when the standard deviations of the given values will equate to zero.

Additionally, if you want to change the data from formula to values and vice versa you can hit the Ctrl+` (grave accent) in the keys. In addition, you can do the change of viewing by hitting the Formulas bar, and in Formula Auditing group slot the Show Formulas option.

CODE Excel Formula

Author Zaheer    Category Formulas     Tags ,

In Excel, Code Function returns the ASCIIValue of the character or first character in the cell.

The syntax for Code Function is: Code (text)

Text is specified character to retrieve ASCIIValue. If there’s more than one character, the function would return ASCIIValue for first character and just ignore all characters after the firsts.

Applies to: Excel 2003, Excel 2007, Excel XP and Excel 2000

How to Use Excel Code Function?

Excel’s Code functions determine the numeric demonstration for the initial character in the particular text string. The value is firmed by the character set used. This would be Macintosh character set for the Macintosh computers as well as ANSI characters for the Windows computer. Here are the following steps that will show you how you can use Excel Code function.

  • Study the syntax for Code. It’s Code (text_string) it is where text_string is text value. The Code will go again the code for first character in the text_string.
  • Use cell reference, named series or text string as an applicable input for Code function.  Code functions would return the #Value! when the case can’t be determined to text value.
  • Come across the following easy examples for Code uses of:

Code (“A”) =65, Code (“B”) =66, Code (“C”) =67 and so on. These results assume that you are running Excel on a Windows computer.

Examine more complex uses of the function of the code:

Code (“Alphabet”) = 65. Note that only the code for the first character is returned.
Code (-1) = 45. The entry of -1 is implicitly converted to text “-1″ and the ASCII code “-” (the script) is 45.

Code (CHAR (23)) = 23. This usage shows that the function of the code is the inverse of Char.

Code (“”) = # VALUE! The empty text can not be resolved in a text value and therefore returns the #! The error code

Study of the ASCII character values ??to verify the results of code. Note that the values ??of characters 0 to 31 are printable and will be represented by a small square in Windows.

How to Use VBA Code in Excel?

You can find more than a few pieces of code in the pages of this website or a website, and decide. Add one of your books. The majority of the code can be added as follows:

Excel Functions: Text, ABS and the number or date formats

The text () and functions ‘and’ is very useful to include the numerical values ??of cells within meaningful phrases that can be understood by a layman. The statements can be built that combine words and numeric values ??(for example: “The budget for £ 23,000 was spent in April”).

The ‘and’ symbol is not strictly a function. It is an operator which can be used to join (or concatenate) and two chains or fragments of text.

For example: = “The difference is” and D2 in cell D2 contains “adverse” or “favorable”

If you join a piece of text and a number or date of the appearance and format of the series can be unpredictable unless you are using the text function. The TEXT function converts a number to text format and also gives you the look you need.

It takes the form: = TEXT (value, “FormatCode”).

The complicated aspect of this role includes FormatCodes. Some of them are shown in the following example and tables. Alternatively, you can use Excel Help and look for the ‘format numbers: Custom formats.
