GAMMA.INV function

The GAMMA.INV function returns the value of the inverse gamma cumulative distribution function for the specified probability, alpha, and beta parameters.

Parts of a GAMMA.INV formula

GAMMA.INV(probability, alpha, beta)

Part	Description	Notes
`probability`	The input to the inverse gamma distribution function.	Must be between 0 and 1.
`alpha`	The shape of the gamma distribution.	Must be positive. The sign of significance is ignored.
`beta`	The scale of the gamma distribution.	Must be positive.
