Coale-Demeny regional model life tables

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

sex

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

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).

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
