Method new()

Create a new GPD object.

Usage

GPD$new(loc = 0, scale = 1, shape = -0.1)

Arguments

[double] location parameter

scale

[double] scale parameter

shape

[double] shape parameter

Returns

A new `GPD` object.

---

Method fit()

Fit method

GPD$fit(Y, loc = NULL)

Arguments

Y

[vector] Dataset to infer the histogram

loc

[double] location parameter, if NULL used min(Y)

Examples

## Generate sample
loc   = 0
scale = 0.5
shape = -0.3
gpd = ROOPSD::GPD$new( loc = loc , scale = scale , shape = shape )
X   = gpd$rvs( n = 1000 )

## And fit parameters
gpd$fit( X , loc = 0 )
