LTabr: an abridged lifetable based on M(x)

In timriffe/DemoDecomp: Decompose Demographic Functions

an abridged lifetable based on M(x)

Description

Implements the abridged lifetable formulas given in the supplementary material to Andreev et. al. (2012). An entire lifetable is calculated, but only life expectancy at birth is returned.

Usage

LTabr(Mx, Age = c(0, 1, cumsum(rep(5, length(Mx) - 2))), radix = 1e+05)

Arguments

Mx	numeric vector of abridged mortality rates.
Age	integer, abridged age lower bounds.
radix	numeric. Can be anything positive.

Details

Chiang's a(x) is assumed in the following way: a(0) = 0.07 + 1.7 * M(0), a(1) = 1.6, a(\omega) = \frac{1}{M(\omega)}, and all others are assumed at mid interval. The last age is assumed open. Everything else is pretty standard.

Value

numeric life expectancy at birth
