Computes $$ P({}_{n|}\ddot{a}_x) = \frac{{}_{n|}\ddot{a}_x} {\ddot{a}_{x:\overline{n}|}}. $$

Usage

PnAdotx(x, n, i, model = NULL, ..., tbl = NULL)

Arguments

x

Issue age. May be scalar or vector.

n

Positive integer deferral period. May be scalar or vector.

i

Effective annual interest rate. May be scalar or vector.

model

Optional parametric survival model.

...

Additional parameters passed to the actuarial functions.

tbl

Optional life table object. Supply by name.

Value

Numeric vector of net annual premiums.

Examples

PnAdotx(
  40,
  n = 20,
  i = 0.05,
  model = "uniform",
  omega = 100
