Technically, a double robust estimation has two parts, an inverse probability of treatment weighting (IPTW) section and an “augmentation” section. In the equation belowas explained by Jason Roy of the University of Pennsylvania,Yis the outcome, A is whether the individual received the treatment,...
Abbreviations: PSM, propensity score matching; DFS, disease-free survival; OS, overall survival; MPR, major pathological remission.

We sought to compare outcomes of healthcare resource utilization (HCRU), by PAP adherence, in OSA patients with AFib, systolic HF, and diastolic HF using two propensity score methods, propensity score matching (PSM) and inverse probability weighting (IPW). Methods US administrative claims data ...
It is also referred to as “inverse probability of participation/attrition weighting” (IPPW/IPAW) in the literature [6,7,8]. Originally developed for reducing the effects of confounding in observational studies (propensity score method) [9], the IPW method was extended to correct for selection...

Typically covariate adjustment is conducted using regression analysis, however recently, Inverse Probability of Treatment Weighting (IPTW) using the propensity score has been proposed as an alternative method. For a continuous outcome it has been shown that the IPTW estimator has the same large ...
We engage in Monte Carlo simulations to evaluate the performance of inverse probability of treatment weighting (IPTW) with 10 treatments, estimating the propensity scores using Generalized Boosted Models. We assess the performance of IPTW under three different scenarios representing treatment allocations,...
Propensity score and inverse weighting methods both attempt to achieve this goal. Inverse probability weighting is the method based on Horvitz and Thompson (1952) while propensity score is based on Rosenbaum and Rubin (1983). Because they are the most prevalent methods in longitudinal studies, ...
Propensity score (PS) methods, including inverse probability of treatment weighting (IPTW) analysis, are increasingly applied to complex survey data in geriatric studies to infer causal effects. However, the comparative effectiveness of various PS estimation methods, particularly novel machine learning ...
