Unobserved population heterogeneity and its impact on life-table estimates motivated the introduction of frailty models three decades ago. The concept of latent individual differences repeatedly proved useful in applications and led to important insights, in demography and beyond. This talk reviews the influence that the seminal paper by Vaupel et al. had on demographic research in general and ...

t Parametric models for the entire age pattern of mortality have been suggested by Heligman and Pollard (1980) and Carriere (1992). The former is designed to fit the classical mortality pattern while the latter is supported by a statistical theory. Insights into their papers motivate us to consider a variation of the Heligman-Pollard model. We also apply these models to the 1993 Hong Kong Assur...

This manuscript is concerned with relating two approaches that can be used to explore complex dependence structures between categorical variables, namely Bayesian partitioning of the covariate space incorporating a variable selection procedure that highlights the covariates that drive the clustering, and log-linear modelling with interaction terms. We derive theoretical results on this relation...

OBJECTIVES To explore various methods to quantify the burden of mortality, with a special interest for the more recent method at the core of calculations of disability adjusted life years (DALY). DESIGN Various methods calculating the age schedule at death are applied to two historical life table populations. One method calculates the "years of life lost", by multiplying the numbers of deaths...

For some time I have wondered why graphical methods for categorical data are so poorly developed and little used compared with methods for quantitative data. For quantitative data, graphical methods are commonplace adjuncts to all aspects of statistical analysis, from the basic display of data in a scatterplot, to diagnostic methods for assessing assumptions and finding transformations, to the ...

When applying model-driven architecture to component models, a significant issue is to address challenges such as component architecture transformation, compositional consistency analysis, and component code synthesis in a reusable way. Mostly, this is due to the substantial differences among abstractions of component models. As a remedy, the paper presents Periodic Table of Component Models (P...

Life expectancy continues to grow in most Western countries; however, a major remaining question is whether longer life expectancy will be associated with more or fewer life years spent with poor health. Therefore, complementing forecasts of life expectancy with forecasts of health expectancies is useful. To forecast health expectancy, an extension of the stochastic extrapolative models develop...
