WebJan 17, 2024 · When individual-level data are available, frequentist approaches may estimate a causal effect using g-computation, propensity score (PS)-based weighting, PS-based stratification, PS-based matching, targeted maximum likelihood estimation (TMLE), etc. [10,11,12,13,14]. WebThe key step in targeted maximum likelihood estimation is updating a density estimate, such as the initial estimate described by the above logistic regression fits. A parametric model, with parameter , is constructed that (i) equals the current density estimate at = 0, and (ii) has score at = 0equal to the efficient influence function. nantong lead solar technology co. ltd https://corpoeagua.com
