  1. A is the age-independent initial mortality rate, B the acceleration of age-specific mortality rate and S the degree of deceleration of mortality rate at advanced ages. These parameters are given for the three separate replicates and the average overall survival curve. Note that in replicate 2, the S value of zero indicates that there is no deceleration of mortality rate, reducing the logistic model to the Gompertz model. 95% CI is the 95% confidence interval of the parameter as obtained by WinModest.
