cdmltw: 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).

Value

A list containing two 21 element vectors, one 25 element vector 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

e10

the 25 mortality levels as life expectancy at age 10

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

Details

Provides region-specific 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).

The regions are West (cdmltw), East (cdmlte), South (cdmlts), and North (cdmltn).
