Web26 aug. 2024 · Inverse probability of treatment weighting (IPTW) can be used to adjust for confounding in observational studies. IPTW uses the propensity score to balance baseline patient characteristics in the exposed and unexposed groups by weighting each individual in the analysis by the inverse probability of receiving his/her actual exposure. Web1 dec. 2024 · ipcw( formula, data, method, args, times, subject.times, lag = 1, what, keep = NULL ) Arguments. formula: A survival formula like, Surv(time,status)~1, where as usual status=0 means censored. The status variable is internally reversed for estimation of censoring rather than survival probabilities. Some of the ...
