Propensity scoreWeightingCovariate balanceCausal inferenceOverlap weighting (OW), using weights defined as the probability of receiving the opposite treatment, is a relatively new, alternative propensity score (PS)-based weighting technique used to adjust for confounding when estimating causal treatment ...
choosing an algorithm for matching based on that propensity score (e.g., nearest-neighbor matching with or without replacement); 3. checking for overlap and common support; 4. checking the quality of the match; and 5. assessing the sensitivity of the estimates of treatment effects. They also...

matching requires large samples with a reasonable spread of baseline variables across the population and substantial overlap between the comparison groups. The process generally includes: (1) choosing variables to be included in the propensity score, (2) choosing matching and weighting strategies to ...
