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