evd (version 1.2-2)

dens: A Density Plot for an evd Object

Description

A density plot for an evd object. The density of the fitted model is plotted with a rug plot and (optionally) a non-parameteric estimate.

Usage

dens(x, adjust = 1, nplty = 2, jitter = FALSE, main = "Density Plot", 
    xlab = "Quantile", ylab = "Density", ...)

Arguments

x

An object of class "evd".

adjust

Adjust the smoothing bandwidth for the non-parametric estimate. See density for details.

nplty

The line type of the non-parametric estimate. Use zero to suppress.

jitter

Logical; if TRUE, the (transformed) data are jittered to produce the rug plot. See jitter. This need only be used if the data contains repeated values.

main

Title of plot.

xlab,ylab

Labels for x and y axes.

...

Other plot parameters.

Details

For non-stationary models the data are transformed to stationarity. The plot then corresponds to the distribution obtained when all covariates are zero.
