Web19 de mar. de 2004 · A simple variance estimator with good small sample properties has recently been introduced by Goetghebeur and Ryan . Following Rubin and Schenker ( 1991 ), they proposed to impute data (in this case, sampled values of the unobserved covariates) and to obtain naïve point estimates and variance estimates for the parameters of interest. Web17 de jul. de 2009 · The Breslow-type estimator has been proposed for estimating the nonparametric component in some inefficient estimation procedures. We show that introducing weights into this estimator leads to nonparametric maximum likelihood estimation, with the weights depending on the martingale residuals.
