GAMMAINV

Excel Functions

Get inverse of the gamma cumulative distribution

Syntax

EXCEL 
=GAMMAINV(probability, alpha, beta)

Arguments

Parameter Description
probability The probability associated with the gamma distribution (must be between 0 and 1).
alpha The shape parameter of the distribution.
beta The scale parameter of the distribution.

Return Value

The value of a probability

Details

The GAMMAINV function returns the value at which the cumulative gamma distribution reaches a specified probability. For better accuracy and consistency with other modern statistical functions, it is recommended to use the GAMMA.INV function. GAMMA.INV uses the same arguments and provides the same core functionality with improved numerical precision. See the GAMMA.INV function for more details and examples.
