GAMMAINV
This function returns the inverse of the gamma cumulative distribution.
Syntax
GAMMAINV(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 = GAMMADIST(x,...), then GAMMAINV(p,...) = x.
Examples
GAMMAINV(A3,3,4)
GAMMAINV(0.8902,R3C8,R3C9)
GAMMAINV(0.75,2,3) gives the result 8.0779035867
