Table 2. Estimates of two-type gender-specific Gompertz mortality model.

Results are based on estimating Eq. (11) separately for each gender using the same data as in Table 1 Standard errors are in parentheses. The estimation for females led to a single type model. The final column reports the total log likelihood.
