Using Parametric Statistical Models to Estimate Mortality Structure: The Case of Taiwan

Shih-Chieh Chang

Abstract

A mixture parametric model is used to analyze the changing pattern of Taiwanese mortality from 1926 to 1991. Three different age ranges are modeled as mixtures of extreme value distributions, namely the Weibull, inverse Weibull, and Gompertz distributions. The results show a significant improvement of mortality over the years.

Key words and phrases: mixture, extreme value distribution, Weibull, inverse-Weibull, and Gompertz
