WebSep 5, 2024 · IPW, also known as inverse probability of treatment weighting, is the most widely used balancing weighting scheme. IPW is defined as wi = 1 / ˆei for treated units and wi = 1 / (1 − ˆei) for control units. IPW assigns to each patient a weight proportional to the reciprocal of the probability of being assigned to the observed treatment group.
