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")
Value
A numeric value representing joint survival probability.
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).
