Age-specific mortality rates are estimated and projected using the Kannisto, Lee-Carter and related methods as described in Sevcikova et al. (2016).
The main functions are:
Functions contained in the package can be used for both, 5-year and 1-year age groups.
Other methods for forecasting mortality rates are available:
pmd: pattern of mortality decline
mlt: model life tables, using UN lookup tables. Note that the tables were updated in version 2.6-0 (October 2021). For previous version of the tables install 2.5-0, e.g.
logquad: log-quadratic mortality model
mortcast.blend: combining two different methods
A life table can be constructed using the life.table function.
