The gamma distribution is a family of continuous probability distributions with ositive parameters r, A and a density given by f(x) = -x"* when x > 0, and zero otherwise. e I(r) Iere I'(r) is called the gamma function and defined by I(r) = So x"-le»dx. See ttps://en.wikipedia.org/wiki/Gamma_function for more details. Say X - gamma(r, X) if X has the density above. The following problems are m the properties of gamma distributions.
