WebAug 26, 2024 · Inverse probability of treatment weighting (IPTW) can be used to adjust for confounding in observational studies. IPTW uses the propensity score to balance … WebThese strategies are all based on propensity scores, namely matching or pruning, IPTW (inverse probability treatment weighting) and entropy balancing. Methods to evaluate these strategies are presented. A logit model is employed with 87 predictors to estimate the propensity score or to estimate the entropy balancing weights.
WebOnce your propensity score is estimated, it’s important to make sure the measured covariates are balanced in order to reduce overt bias (Harder, 2010).
