In lifecontingencies: Financial and Actuarial Mathematics for Life Contingencies

Function to evaluate the n-year endowment insurance

Description

This function evaluates the n-year endowment insurance.

Usage

AExn(actuarialtable, x, n, i=actuarialtable@interest,  k = 1, type = "EV", power=1)

Arguments

actuarialtable	An actuarial table object.
x	Insured age.
n	Length of the insurance.
i	Rate of interest. When missing the one included in the actuarialtable object is used.
k	Frequency of benefit payment.
type	A string, either "EV" for expected value of the actuarial present value (default) or "ST" for one stochastic realization of the underlying present value of benefits. Alternatively, one can use "expected" or "stochastic" respectively (can be abbreviated).
power	The power of the APV. Default is 1 (mean)

Details

The n-year endowment insurance provides a payment either in the year of death or at the end of the insured period.

Value

A numeric value.

Note

When type="EV" the function calls both Axn and Exn.
