mdt-class: Class '"mdt"'

In lifecontingencies: Financial and Actuarial Mathematics for Life Contingencies

Class "mdt"

Description

A class to store multiple decrement tables

Objects from the Class

Objects can be created by calls of the form new("mdt", name, table, bottomCompletionSurvival, ...). They store absolute decrements. bottomCompletionSurvival (default 0.99) is the one-year survival ratio used to synthetically back-fill ages below the lowest age supplied in table; it does not affect rows for ages actually supplied.

Slots

name:

The name of the table

table:

A data frame containing at least the number of decrements

Methods

getDecrements

signature(object = "mdt"): return the name of decrements

getOmega

signature(object = "mdt"): maximum attainable age

initialize

signature(.Object = "mdt"): method to initialize the class

print

signature(x = "mdt"): tabulate absolute decrement rates

show

signature(object = "mdt"): show rates of decrement

coerce

signature(from = "mdt", to = "markovchainList"): coercing to markovchainList objects; available only when the optional markovchain package is installed

coerce

signature(from = "mdt", to = "data.frame"): coercing to data.frame

summary

signature(object = "mdt"): it returns summary information about the object

Note

Currently only decrements storage of the class is defined.
