WebAug 28, 2024 · An empirical probability density function can be fit and used for a data sampling using a nonparametric density estimation method, such as Kernel Density Estimation (KDE). An empirical cumulative distribution function is called the Empirical Distribution Function, or EDF for short. WebThe probability density function for gamma is: f ( x, a) = x a − 1 e − x Γ ( a) for x ≥ 0, a > 0. Here Γ ( a) refers to the gamma function. gamma takes a as a shape parameter for a. When a is an integer, gamma reduces to the Erlang distribution, and when a = 1 to the exponential distribution.
