GammaInv() returns the inverse of the accumulated probability of the Gamma distribution.
Syntax:
GammaInv(prob, k, θ)
Return data type: number
| Argument | Description |
|---|---|
| prob | A probability associated with the Gamma-probability distribution. It must be a number between 0 and 1. |
|
k |
A positive number defining the shape parameter. |
| θ | A positive number defining the scale parameter. |
This function is related
to the GammaDist function in the following way:
If prob = GammaDist(value, k, θ), then GammaInv(prob, k, θ) = value
