pxyt: Functions to evaluate joint survival probabilities.

In spedygiorgio/lifecontingencies: Financial and Actuarial Mathematics for Life Contingencies

Functions to evaluate joint survival probabilities.

Description

These functions evaluate survival and death probabilities for two heads.

Usage

exyt(objectx, objecty, x, y, t, status = "joint")

pxyt(objectx, objecty, x, y, t, status = "joint")

qxyt(objectx, objecty, x, y, t,  status = "joint")

Arguments

objectx	lifetable for life X.
objecty	lifetable for life Y.
x	Age of life X.
y	Age of life Y.
t	Time until survival has to be evaluated.
status	Either "joint" for the joint-life status model or "last" for the last-survivor status model (can be abbreviated).

Value

A numeric value representing joint survival probability.
