tdata {ercv}

Transforms a heavy-tailed sampled to non-heavy tailed

Description

Transformation of a sample with assumption of heavy-tail to a sample with non-heavy tail.

Usage

tdata(data, threshold = NA, nextremes = NA, sigma=NA)

Arguments

data

a numeric vector.

threshold

a threshold value (either this or nextremes must be given but not both).

nextremes

the number of upper extremes to be used (either this or threshold must be given but not both).

sigma

the scale parammeter divided by shape parameter in generalized Pareto distribution.

Value

The transformed data as a numerical vector.
