Breslow and Holubkov (J Roy Stat Soc B 59:447–461 1997a) developed semiparametric maximum likelihood estimation for two-phase studies with a case–control first phase under a logistic regression model and noted that, apart for the overall intercept term, it was the same as the semiparametric estimator for two-phase … WebHowever, an unnatural and undesirable feature of the Breslow estimator is that, its estimated survival probability will never reaches zero even if the last observation is an event.

Interpretation of Breslow Estimator for Baseline hazard

Web1 Answer. Yes, it probably shouldn't be used as an estimate of hazard, and as Elvis points out the rest of the paper notes that Breslow didn't really intend it for that purpose. The estimator should not be viewed as such, for it is inconsistent as an estimator of λ in the Cox model (although erroneous use of (1.2) has occurred in the ... WebThe censoring indicator.
