gamma_est: Maximum-likelihood estimation of parameters for the gamma distribution

Description

The maximum-likelihood estimators for the shape and scale parameters of a gamma distribution are computed due to the method of Bhattacharya (2001).

Usage

gamma_est(data)

Arguments

data

vector of positive valued observations

Value

returns a bivariate vector containing (shape,scale) estimated parameter vector.
