Fractional failure probability from a life table

Computes \({}_t q_x = 1 - {}_t p_x\) for \(0 \le t \le 1\).

Usage

tqx_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 \({}_t q_x\) values.
