EVTfit: EVT fit

Description

Create an S3 object using an EVT (Extreme Value Theory) fit.

Usage

EVTfit(gamma, endpoint = NULL, sigma = NULL)

Arguments

gamma

Vector of estimates for \(\gamma\).

endpoint

Vector of endpoints (with the same length as gamma). When NULL (default), a vector containing Inf for each value of gamma will be used.

sigma

Vector of scale estimates for the GPD (with the same length as gamma). When NULL (default), not included in the object.

Value

An S3 object containing the above input arguments.

Details

See Reynkens et al. (2017) and Section 4.3 of Albrecher et al. (2017) for details.
