# GAMMA.INV

## Content

This function returns the inverse of the gamma cumulative distribution.

## Syntax

`GAMMA.INV(p, alpha, beta)`

## Arguments

This function has these arguments:

| Argument | Description |
| -------- | ----------- |
| *p* | [Required] Probability |
| *alpha* | [Required] Alpha parameter of the distribution |
| *beta* | [Required] Beta parameter of the distribution |

## Remarks

This function calculates the inverse of the F probability distribution, so if p = GAMMA.DIST(x,...), then GAMMA.INV(p,...) = x. The standard gamma distribution is returned if  *beta* = 1.

## Examples

`GAMMA.INV(A3,3,4)`
`GAMMA.INV(0.8902,R3C8,R3C9)`
`GAMMA.INV(0.75,2,3)` gives the result 8.077903586669088
