angular.plot: Angular density plot.

In ExtremalDep: Extremal Dependence Models

Angular density plot.

Description

This function displays the angular density for bivariate and trivariate extreme values models.

Usage

angular.plot(model, par, log, contour, labels, cex.lab, cex.cont, ...)

Arguments

model	A string with the name of the model considered. Takes value "PB" (Pairwise Beta), "HR" (Husler-Reiss), "ET" (Extremal-t), "EST" (Extremal Skew-t), TD (Tilted Dirichlet) or AL (Asymmetric Logistic).
par	A vector representing the parameters of the model.
log	A logical value specifying if the log density is computed (default is TRUE).
contour	A logical value; if TRUE the contour levels are displayed. Required for trivariate models only.
labels	A vector of character strings indicating the labels. Must be of length 1 for bivariate models and 3 for trivariate models.
cex.lab	A positive real indicating the size of the labels.
cex.cont	A positive real indicating the size of the contour labels.
...	Additional graphical arguments for the hist() function when style="hist".

Details

The angular density is computed using the function dExtDep with arguments method="Parametric" and angular=TRUE.

When contours are displayed, levels are chosen to be the deciles.
