Last-survivor annuity functions — last_survivor

Computes temporary and whole-life annuities for two lives under the last-survivor status.

Usage

adotxybarn(x, y, n, i, tbl = NULL, model = NULL, ...)

axybarn(x, y, n, i, tbl = NULL, model = NULL, ...)

adotxybar(x, y, i, tbl = NULL, model = NULL, ..., k_max = 5000L, tol = 1e-12)

axybar(x, y, i, tbl = NULL, model = NULL, ..., k_max = 5000L, tol = 1e-12)

Arguments

x: Age of the first life. May be scalar or vector.
y: Age of the second life. May be scalar or vector.
n: Term in years. May be scalar or vector.
i: Effective annual interest rate. May be scalar or vector.
tbl: Optional life table object.
model: Optional parametric survival model.
...: Additional parameters passed to the survival model or life-table functions.
k_max: Maximum number of terms used for an infinite series.
tol: Numerical tolerance used to assess convergence.

Value

A numeric vector of actuarial present values.
