Gamma distribution Mean (With a shape parameter α and a rate parameter β )


In probability theory and statistics, the gamma distribution is a two-parameter family of continuous probability distributions. The parameterization with α and β is more common in Bayesian statistics.The gamma distribution is the maximum entropy probability distribution for a random variable X for which E(X) is fixed and greater than zero.
