WebMar 7, 2024 · Overlap Weights for Causal Inference/Comparative Effectiveness Research . Basic Idea. To compare two treatments (say one treatment and one control), the overlap weight (OW) for each unit is the probability that unit is assigned to the opposite group, that is, 1-PS for the treated units, and PS for the control units, where PS is the propensity score … WebR codes explained - Calculating IPTW. At each time point, we calculate the weight using the ipwpoint function.
