WebIn statistics, the generalized Pareto distribution (GPD) is a family of continuous probability distributions. It is often used to model the tails of another distribution. It is specified by three parameters: location , scale , and shape . [2] [3] Sometimes it is specified by only scale and shape [4] and sometimes only by its shape parameter.
