Targeted maximum likelihood estimator
WebFeb 22, 2010 · This iterative targeted maximum likelihood updating step makes the resulting estimator of the causal effect double robust in the sense that it is consistent if either the initial estimator is consistent, or the estimator of the optimal fluctuation function is consistent. The optimal fluctuation function is correctly specified if the conditional ... WebTargeted maximum likelihood estimation (van der Laan and Rubin, 2006; van der Laan and Rose, 2011) is a general methodology for semiparametric efficient substitution estimation (Bickel et al., 1993; van der Laan and Robins, 2003; Tsiatic, 2007) of causal parameters consisting of two steps.
