The role of genes in the length of life

Abstract:
We consider data from the Danish twin registry and aim to study in
detail how lifetimes for twin-pairs are correlated.  We consider
models where we specify the marginals using a regression structure,
here Cox's regression model or the additive hazards model.  The best
known such model is the Clayton-Oakes model. This model can be
extended in several directions. One extension is to allow the
dependence to parameter to depend on covariates. Another extension is
to allow the dependence to be piecewise constant cross-hazard ratio
(CHR) models. We show how both these models can be implemented for
large sample data, and suggest a computational solution for obtaining
standard errors for such models for large registry data.
