plot.gpdbiv: Plot Fitted Bivariate GPD Model

In evir: Extreme Values in R

Description

Provides a number of plots summarising a bivariate GPD model fitted using the bivariate POT method. See the examples below.

Usage

## S3 method for class 'gpdbiv'
plot(x, extend = 1.1, n.contours = 15, ...)

Arguments

x	a gpdbiv object
extend	optional argument expressing how far x-axis should extend as a multiple of the largest data value.
n.contours	number of contours in bivariate contour plots
...	other graphics parameters

Details

Option 1 plots the threshold exceedance data; option 2 plots contours of the fitted bivariate distribution function in the joint upper tail (above both thresholds); option 3 plots corresponding contours of the fitted joint survival function; plots 4 and 5 show the fitted tails of the marginal distributions.
