I'm looking for work on changes with age in the
degree of sex-biased mortality in human populations.
I am aware of such theoretical work as Vaupel and
Yashin, 1985, Amer. Statist. 39:176-185 that may be relevant.
Does anyone know of medical literature that might
be appropriate to look at? A more general
theme that might exist in the medical literature,
as well as literature on measuring selection in
natural populations, is the effect of cohort heterogeneity
on measures of survival. I have just started looking
at this problem, and a few good references would be
most helpful to me. Any thoughts?
