cvevi: Coefficient of variation for a given extreme value index

Description

The coefficient of variation for a given extreme value index in the generalized Pareto distribution.

Usage

cvevi(evi)

Arguments

evi

extreme value index. In particular, the shape parameter of a generalized Pareto distribution. It has to satisfy evi < 1/2.

Value

A numerical value containing the coefficient of variation for the given extreme value index.
