Title: On Collapsibility
Author(s): David Oakes*+
Companies: University of Rochester
Address: Dept Biostatistics and Computational Biology, Rochester, NY, 14642,
Keywords: accelerated life model ; hazard function ; multiple time-scales ; survival analysis
Abstract:

The notion of collapsibility provides a simple approach to quantification of the contributions to the overall risk of failure due to multiple time scales; for example, the months and miles a car has been driven. An epidemiologic application could involve the influence on mortality of the age of a cigarette smoker and pack-years of cigarettes consumed. This talk will review some recent work in the area of collapsibility.
