Gompertz Models

A new nonlinear regression package in Excel for simple mortality models is available here:

The best fit model is a combination of a model derived from the first exit time theory of a stochastic process with a Gompertzian correction for the ages from 15 to 30 years.
For the best fit model go to the Health State Model webpage
