# Gamma distribution Mean (With a shape parameter k and a scale parameter θ)

## Description

In probability theory and statistics, the gamma distribution is a two-parameter family of continuous probability distributions. The parameterization with k and θ appears to be more common in econometrics and certain other applied fields. The gamma distribution is the maximum entropy probability distribution for a random variable X for which the arithmetic mean is fixed and greater than zero.
