Calculating survival probabilties given mortality in the FLBiol object

Description

For an FLBiol object with the mortality-at-quant this method calculates the associated survival probability-at-quant. This can be later used by the r() method. The calculation can be carried out either by year or by cohort.

Usage

survprob(object, ...)

Arguments

Details

Calculates the survival probability-at-quant given the mortality information in an FLBiol-class object - survival probability from one year to the next is simply exp(-M) and the survival probaiblity to a given quant is merely the product along the quant dimension of the individual survival probabilities.

Value

An object of class FLQuant-class.
