Transformed outcome formula and results. A challenge with most real-life data-sets is that treatments are not randomly assigned. This produces a bias in the data-set, causing the predicted uplifts to also be biased.
WebInverse probability weighting (IPW) is a commonly used method to correct this bias. It is also used to adjust for unequal sampling fractions in sample surveys. This article is a review of the use of IPW in epidemiological research. We describe how the bias in the complete-case analysis arises and how IPW can remove it.
