Coale-Demeny Model Life Tables

Description

Coale-Demeny regional model life tables

Usage

cdmltw(sex = "F")
cdmlte(sex = "F")
cdmlts(sex = "F")
cdmltn(sex = "F")

Arguments

sex female or male life tables. Defaults to 'F' (female).

Details

Provides model life tables for 25 different levels of mortality, indexed by life expectancy at age 10 (with 1 being the lowest and 25 being the highest life expectancy at age 10).

Value

A list containing two 21 element vectors and eight 25 x 21 matrices: 25 mortality levels by 21 age classes. The eight matrices contain the standard columns of a life table for each mortality level:

age the 21 age classes
width widths of the 21 age classes
lx survival probabilities to exact age x
nqx probabilities of death between ages x and x+n
nax person-years lived by those dying between ages x and x+n
ndx proportion of all deaths occurring between ages x and x+n
nLx person-years lived in the interval x to x+n
nmx central death rate in the interval x to x+n
Tx person-years of life remaining to the cohort at age x
ex life expectancy at age x

Examples

## Generate West model life table family for females
Wf <- cdmltw()

## Plot survivorship for the 25 levels
plot(Wf$age,Wf$lx[1,], type="l", xlab="Age", ylab="Survivorship")
for(i in 2:25) lines(Wf$age, Wf$lx[i,])
