scaleParameter,AnnualAggLossDevModelOutput-method

The object of type <code>AnnualAggLossDevModelOuput</code> from which to plot and/or return the scale parameter.

object

The scale parameter is allowed to vary with development time. Setting <code>column</code> results in the plotting and returning of the scale parameter corresponding to that column. Default value is <code>1</code>.

column

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

plotDensity

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

plotTrace

A method to plot and/or return the posterior of the scale parameter for the Student-\(t\) measurement equation for models in BALD.

Bayesian analysis of loss development on insurance triangles or 'BALD' is a Bayesian model of developing aggregate loss triangles in property casualty insurance. This actuarial model makes use of a heteroskedastic and skewed t-likelihood with endogenous degrees of freedom, employs model averaging by means of Reversible Jump MCMC, and accommodates a structural break in the path of the consumption of benefits. Further, the model is capable of incorporating expert information in the calendar year effect. In an accompanying vignette, this model is applied to two widely studied General Liability and Auto Bodily Injury Liability loss triangles. For a description of the methodology, see Frank A. Schmid (2010) <doi:10.2139/ssrn.1501706>.
