pxyt: 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.
