Reversionary annuity functions — reversionary

Computes reversionary whole-life annuities payable to one life after the death of the other life.

Usage

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

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

x: Age of the first life. May be scalar or vector.
y: Age of the second life. 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.

A numeric vector of actuarial present values.

ax_y() computes an annuity payable to the second life after the death of the first life.

ay_x() computes an annuity payable to the first life after the death of the second life.
