The Nakagami distribution or the Nakagami-m distribution is a probability distribution related to the gamma distribution. It has two parameters: a shape parameter and a second parameter controlling spread, . Its probability density function (pdf) is f(x;,mu,omega) = frac{2mu^mu {Gamma(mu)omega^mu}x^{2mu-1}expleft(-frac{mu}{omega}x^2right). Its cumulative distribution function is F(x;,mu,omega) = Pleft(mu, frac{mu}{omega}x^2right), where P is the incomplete gamma function (regularized).
