rateOfDecay {BALD} R Documentation

## A generic function to plot and/or return the esimtated rate of decay vs development year time.

### Description

A generic function to plot and/or return the esimtated rate of decay vs development year time.

### Arguments

 `object` The object from which to plot and/or return the estimated rate of decay. `plot` A logical value. If `TRUE`, the plot is generated and the statistics are returned; otherwise only the statistics are returned.

### Details

The simplest definition of the rate of decay is the exponentiated first difference of the consumption path. This is a generic function to allow for the retrieval and illustration of the rate of decay. See `vignette('BALD')`.

### Value

Mainly called for the side effect of plotting. Also returns the plotted statistics. Returned invisibly.

`rateOfDecay("StandardAnnualAggLossDevModelOutput")` `rateOfDecay("BreakAnnualAggLossDevModelOutput")` `consumptionPath` `rateOfDecayTracePlot`

### Examples

```rm(list=ls())
library(BALD)
data(IncrementalGeneralLiablityTriangle)
IncrementalGeneralLiablityTriangle <- as.matrix(IncrementalGeneralLiablityTriangle)
print(IncrementalGeneralLiablityTriangle)
data(PCE)
PCE <- as.matrix(PCE)[,1]
PCE.rate <- PCE[-1] / PCE[-length(PCE)] - 1
PCE.rate.length <- length(PCE.rate)
PCE.years <- as.integer(names(PCE.rate))
years.available <- PCE.years <= max(as.integer(
dimnames(IncrementalGeneralLiablityTriangle)[[1]]))
PCE.rate <- PCE.rate[years.available]
PCE.rate.length <- length(PCE.rate)
standard.model.input <- makeStandardAnnualInput(
incremental.payments = IncrementalGeneralLiablityTriangle,
stoch.inflation.weight = 1,
non.stoch.inflation.weight = 0,
stoch.inflation.rate = PCE.rate,
exp.year.type = 'ay',
extra.dev.years=5,
use.skew.t=TRUE)
