\title{Mortality improvement projection functions (Chapter 8)}
\description{
Functions for Chapter 8 Section 8.8 mortality improvement projection.
}
\details{
These functions project one-year death and survival probabilities forward
from a base year and evaluate annuity values under projected mortality.

The standard projection used is
\deqn{q_x^{[Y]} = q_x^{[B]} (1 - AA_x)^{Y-B}}
where:
\itemize{
  \item \eqn{B} is the base year,
  \item \eqn{Y} is the projection year,
  \item \eqn{AA_x} is the mortality improvement factor at age \eqn{x}.
}
}
