Description

These functions evaluates life insurances and annuities on two heads.

Usage

axyn(tablex, tabley, x, y, n, i, m, k = 1, status = "joint", type = "EV", 
payment="advance")
Axyn(tablex, x, tabley, y, n, i, m, k = 1, status = "joint", type = "EV")

Arguments

tablex

Life X lifetable object.

tabley
