This paper presents a study of the performance of simple and counter‐matched nested case‐control sampling relative to a full cohort study. First we review methods for estimating the regression parameters and the integrated baseline hazard for Cox's proportional hazards model from cohort and case‐control data. Then the asymptotic distributional properties of these estimators are recapitulated, and relative efficiency results are presented both for regression and baseline hazard estimation.
