WebFor a general overview of the Breslow estimator, see Lin (2007). Estimators in censorship models in the case of no covariates, i.e., the Kaplan-Meier esti-mator or the Nelson-Aalen estimator, perceived tremendous interest, especially in the 1980s. Established large sample properties include consistency and asymptotic normality (Breslow http://openhymnal.org/Lyrics/Lord_Jesus_Think_On_Me-Southwell.html
