Is There a cap on how Long a Human Can Live? Truncation, Censoring and Extreme Value Modelling

ABSTRACT:
There is sustained and widespread interest in understanding the limit, if any, to the human lifespan.  Apart from its intrinsic interest, changes in survival at extreme ages, say 105 and over, have implications for the biology of ageing and for the sustainability of social security systems. Recent analyses of data on the oldest human lifespans have led to competing claims about survival and to controversy, often due to misunderstandings about the selection of data and to inappropriate use of statistical methods.  One central question is whether the endpoint of the underlying lifetime distribution is finite. This talk discusses the particularities associated with data on extreme lifespans, presents models from Extreme Value Statistics and Demography for their analysis, and outlines ways of handling the truncation and censoring often present in the data.  It provides a critical assessment of earlier work and illustrates the ideas through novel analysis of new datasets on 105+ year lifetimes.

The talk is based on a review paper in Annual Review of Statistics and its Application, written together with Léo Belzile, Anthony Davison, Jutta Gampe and Dimitrii Zholud.
