WebJan 28, 2024 · A: There are a lot of different propensity score weighting methods, but the most common ones that are used in RWE studies are (1) inverse probability of treatment … WebAug 4, 2024 · The inference based on logistic regression is not correct when you incorporate weighting. You need to estimate the variance of the IPTW estimator, which happens to be inversely related to the propensity score. So large weights also lead to large variance estimates and thus larger p-values. (Also, with IPTW, all weights are larger than one since ...

WebConceptually, IPTW attempts to fully adjust for measured confounders by balancing the confounders across levels of treatment with treatment weight. It creates a pseudo-population in which all measured confounders are balanced between different treatment groups (in the example above, it will be between different cannabis use trajectories). WebJan 28, 2024 · Overlap weighting helps overcome some of the limitations of IPTW and SMR weighting. One of the major limitations to both IPTW and SMR weighting is that they’re subject to extreme weights. This occurs when a researcher performs propensity score weighting and certain patients are “up-weighted” very highly such that a single patient can ...
