exposureGrowth: A generic function to plot and/or return the posterior...

In BALD: Robust Loss Development Using MCMC

Description

A generic function to plot and/or return the posterior predicted exposure growth (corresponding to eta in the model). See vignette('BALD').

Arguments

object	The object from which to plot and/or return the posterior predicted exposure growth.
plot	A logical value. If TRUE, the plot is generated and the statistics are returned; otherwise only the statistics are returned.

Value

Mainly called for the side effect of plotting the exposure growth. Also returns a named numeric vector for the median of the posterior for the exposure growth on the real (not log) scale. Returned invisibly.
