GAMMADIST
Returns the gamma distribution.
Syntax
expression.GAMMADIST(arg1, arg2, arg3, arg4);
expression - A variable that represents a ApiWorksheetFunction class.
Parameters
| Name | Required/Optional | Data type | Default | Description |
|---|---|---|---|---|
| arg1 | Required | ApiRange | ApiName | number | The value at which the distribution will be calculated, a nonnegative number. | |
| arg2 | Required | ApiRange | ApiName | number | The alpha parameter of the distribution, a positive number. | |
| arg3 | Required | ApiRange | ApiName | number | The beta parameter of the distribution, a positive number. If this parameter is equal to 1, the function returns the standard gamma distribution. | |
| arg4 | Required | ApiRange | ApiName | boolean | A logical value (true> or false) that determines the function form. If it is true, the function returns the cumulative distribution function. If it is false, the function returns the probability density function. |
Returns
number
