Syntax:
GammaDist(value, k, θ)
Return data type: number

k |
A positive number defining the shape parameter. |
θ | A positive number defining the scale parameter. |
This function is related
to the GammaINV function in the following way:
If prob = GammaDist(value, k, θ), then GammaInv(prob, k, θ) = value
