Mixed Effects Cox Models
Description
Fit Cox proportional hazards models containing both
fixed and random effects. The random effects can have a general form, of which
familial interactions (a "kinship" matrix) is a particular special case.
Note that the simplest case of a mixed effects Cox model, i.e. a single random
per-group intercept, is also called a "frailty" model. The approach is based
on Ripatti and Palmgren, Biometrics 2002.
