WebThe IPW method is generally simple to implement when the missing values have a monotone pattern, and can be carried out in any software package that allows weighted analyses. A key advantage is that, under a correctly specified model for missingness, information on many auxiliary variables can be accommodated, including information on ... WebOct 15, 2024 · The IPW method first models the treatment assignment (on a set of prognostics), then predicts the probability of treatment assignment for each subject in the database and computes the inverse of these probabilities (termed Inverse Probability Weights, or IPW).
