# lt.mx: Life tables from nmx In LifeTables: Two-Parameter HMD Model Life Table System

## Description

Builds a life table by using the mortality rate schedule to calculate the subsequent columns of the table

## Usage

 `1` ```lt.mx(nmx, sex="female", age = c(0,1,seq(5,110,5)), nax=NULL) ```

## Arguments

 `nmx` A vector of age-specific mortality rates `age` The start age of each age interval (will also be the start age for each interval of the subsequent life table) `sex` "male" or "female". The sex determines the nax value for the childhood age intervals using the Coale and Demeney West values when `nax=NULL` and when under 5 mortality is split into 0-1 and 1-4. `nax` A set of nax values for the life table. Must have the same length as `nmx` and if no values are provided, this argument defaults to half the length of the age interval except for the first two childhood age groups.

## Value

 `e0 ` Life expectancy at birth `lt ` A life table with age intervals matching those of the nmx schedule on which the table is built and with columns for age, nax, nmx, nqx, npx, ndx, lx, nLx, Tx, and ex. `lt.5q0` The probability a newborn will die before age 5 `lt.45q15` The probability a 15-year old will die before reaching age 60

## Note

Depending on the mortality rates entered, the resulting life table may have fewer age groups than the length of the mortality rate schedule.
