This Demonstration permits you to construct a baseline mortality table from the Gompertz–Makeham family by specifying the mean and standard deviation of life expectancy at birth. You then create a modified distribution by selecting an inception age—a point in time such as the purchase of a life insurance policy at which you know the individual is alive—and changing the hazard multiple. You then choose various visualizations (such as survival functions and probability density functions) of the resulting statistical distribution. The Demonstration likewise computes the new mean life expectancy both from birth and from some inception point (such as the purchase of a life insurance policy) at which we know the individual is alive.
