Discussing the Strehler-Mildvan model of mortality

BACKGROUND Half a century ago, Strehler and Mildvan (1960) published a seminal paper that, based on certain assumptions (postulates), theoretically ‘justified’ the Gompertz law of mortality. OBJECTIVE We intend to discuss the assumptions and limitations of the original Strehler-Mildvan model (as well as of the Strehler-Mildvan correlation), and to consider some modifications and departures from...

Vitality heterogeneity in the Strehler-Mildvan theory of mortality.

In this paper the Strehler-Mildvan theory of mortality and aging is generalised to cover heterogeneity effects in the population. The theory is based on the concept of environmental shocks that cause death of an individual when exceeding its vitality. Heterogeneity is introduced via the value of the vitality of an individual at birth. The main result of the paper is an expression for the observ...

Study on Robustness of Strehler-mildvan Model

Heterogeneity in the Strehler-Mildvan general theory of mortality and aging.

This study examines and further develops the classic Strehler-Mildvan (SM) general theory of mortality and aging. Three predictions from the SM theory are tested by examining the age dependence of mortality patterns for 42 countries (including developed and developing countries) over the period 1955-2003. By applying finite mixture regression models, principal component analysis, and random-eff...
