Fractional survival probability from a life table

Computes \({}_t p_x\) for \(0 \le t \le 1\) from a discrete life table under one of the standard Chapter 6 assumptions: UDD, constant force, or Balducci.

Usage

tpx_tab(tbl, x, t, assumption = c("udd", "cf", "balducci"))

Arguments

tbl

A life_table object.

x

Numeric vector of integer ages.

t

Numeric vector of fractional durations with \(0 \le t \le 1\).

assumption

One of "udd", "cf", "balducci".

Value

Numeric vector of \({}_t p_x\) values.
