Usage

gompertz(x, scale, fifty.fifty)

Arguments

x	The value(s) at which to evaluate the gompertz function.
scale	The scale parameter should always (or at least for how it is used in BALD) be positive as this indicates an increasing probably of a zero payment.
fifty.fifty	The value at which the gompertz function returns 0.5.

Details

This function is used as the probably of observing a zero payment. (Or one minus the probably of observing a positive payment.) (Note that negative payments are assumed to be missing values.)

Value

An object of type AnnualAggLossDevModelOutputWithZeros and AnnualAggLossDevModelOutput.
