Abstract

Summary

In this paper we discuss an uncomplicated procedure for computing the expected number of deaths in a heterogeneous study sample without requiring any information about the number or distribution of observed deaths. This procedure can thus be used to compare grouped mortality data to a large reference population and also to make predictions about the number of deaths to be expected in the not too distant future based on current population rates. The estimation procedure is introduced in a simple context and later extended to allow for multiple hazard rates, for right censoring, and for competing causes of death.

In dieser Arbeit wird ein unkomplizierter Verfahren zur Errechnung der erwarteten Anzahl von Todesfällen in einer heterogenen Studienstichprobe erörtert, ohne daß hierbei Informationen über die Anzahl oder Verteilung der beobachteten Todesfälle erforderlich wären. Dieses Verfahren kann angewandt werden, um Gruppen von Mortalitätsdaten mit einer großen Bezugsgruppe zu vergleichen und auch um Vorhersagen über die Anzahl zu erwartender Todesfälle in der nicht zu fernen Zukunft auf der Grundlage gegenwärtiger Bevölkerungsraten anzustellen. Das Schätzverfahren wird in einem einfachen Zusammenhang vorgestellt und später erweitert, um multiple Zukunftsraten, richtige Zensierung und konkurrierende Todesursachen einzuschließen.
