In particular, S k is gamma-distributed if the individual random variables are gamma-distributed with the same scale parameter. WebIn probability theory and statistics, there are several relationships among probability distributions. These relations can be categorized in the following groups: One distribution is a special case of another with a broader parameter space. Transforms (function of a random variable); Combinations (function of several variables);
