Plot the hazard model residuals

This function allows to plot the hazard model residuals on the triangle payments.

Usage

# S3 method for class 'clmplusmodel'
plot(x, heat.lim = c(-2.5, 2.5), ...)

Arguments

x

clmplusmodel object, model fit to plot.

heat.lim

limits in the residuals plot.

...

Extra arguments to be passed to the plot function.

Value

No return value, plots the hazard model residuals in triangular form.
