plotFrechet {extremis}

Unit Fréchet Scatterplot in Log-log Scale

Description

This function depicts a scatterplot of bivariate data transformed to unit Fréchet scale.

Usage

plotFrechet(Y, tau = 0.95, raw = TRUE, ...)

Arguments

Y

list with data from which the estimates are to be computed.

tau

value used to threshold the data y; by default treshold = quantile(y, 0.95).

raw

logical; if TRUE, Y will be converted to unit Fréchet scale. If FALSE, Y will be understood as already in unit Fréchet scale.

...

other arguments to be passed to plot.

Details

The solid line corresponds to the boundary threshold in the log-log scale, with both axes being logarithmic.
