exposureGrowthAutoregressiveParameter {BALD}R Documentation

A generic function to plot and/or return the posterior of the autoregressive parameter for the exposure growth for models in BALD.

Description

A generic function to plot and/or return the posterior of the autoregressive parameter for the exposure growth for models in BALD. See vignette('BALD').

Arguments

object

The object from which to plot and/or return the autoregressive parameter which is associated with exposure growth.

plotDensity

A logical value. If TRUE, the density is plotted. If plotTrace is also TRUE, then two plots are generated. If they are both FALSE, then only the statistics are returned.

plotTrace

A logical value. If TRUE, the trace is plotted. If plotDensity is also TRUE, then two plots are generated. If they are both FALSE, then only the statistics are returned.

Value

Mainly called for the side effect of plotting.
