autolayer Method for Predictive Return Levels

Predictive Return Level curve

Usage

# S3 method for predRL
autolayer(object, aes = FALSE, ...)

Arguments

object

An object with class "predRL" corresponding to predictive Return Levels.

aes

Logical. If TRUE the colour and linetype of the line are added to the aesthetic in odred to appear in legends.

...

Further arguments to be passed to geom_line.

Value

An ggplot layer

Details

The argument object contains a table of computed predictive Return Levels, in correspondence with an exceedance probability. The layer shows the tail-quantile function for the predictive distribution.

Note

In practice the predictive distribution for an Extreme-Value model has usually an heavy tail. Therefore at least for small probabilities of exceedance \(p\) the curve is convex (upward concave).
