WebAug 26, 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. Inverse probability weighting is a statistical technique for calculating statistics standardized to a pseudo-population different from that in which the data was collected. Study designs with a disparate sampling population and population of target inference (target population) are common in application. There may be prohibitive factors barring researchers from directly sampling from the target population such as cost, time, or ethical concerns. A solution to this problem is to use …

WebMar 27, 2024 · Generalized linear models (GLMs) are often used with binary outcomes to estimate odds ratios.
