Description
Estimate parameters of a gamma distribution using method of moments.
Usage
1
estGammaParam(mu, sigma)
Arguments
mu
Mean of the gamma distribution.
mu cannot have a negative value.
sigma
Standard deviation of the gamma distribution.
sigma cannot have a negative value.
Details
α (shape) and β (scale) parameters are estimated as:
α = (mu/sigma)^2
β = (sigma^2)/mu
