getqxt
Description
It enables for interpolating age-specific mortality rates for a multi-annual life tables.
Usage
getqxt(Qxt, nag, t)
Arguments
Qxt |
A numerical matrix of Five-ages mortality rates without an age identification column and a time identification row. |
nag |
The number of age groups. |
t |
The number of years. |
Value
qxt : a matrix containing the age-specific mortality rates by age x in rows and year t in columns.
lxt : a matrix containing the evolution of the population of survivors over age x for each year t.
dxt : a matrix containing the theoretical distribution of deaths by age x for each year t.
qxtl : the age-specific mortality rates interpolated using the Lagrange method for each year t.
qxtk : the age specific mortality rates interpolated using the Karup-King method for each year t.
junct_ages : a vector containing the ages where qxtk and qxtl have been joined, for each year t.
