Lee-Carter
\li\-\ˈkɑrtər\
The Lee-Carter model is a mathematical model for projecting historic trends in mortality improvements into the future.
Under this model the average trend in mortality improvements seen historically is assumed to continue. A potential weakness of the Lee-Carter approach is that (in its usual form) it does not readily allow for the ‘golden cohort’ effect, but variants of the model have been developed to account for this.
