WebJul 25, 2024 · Both CALIBERrfimpute and predictive mean matching (PMM) operate under the framework of multivariate imputation using chained equations (MICE), with different MICE imputation methods differing in the process they use to impute missing values. The typical process of MICE-based imputation can be summarized as: (1) Initialization. WebThe predictive mean matching method is also an imputation method available for continuous variables. It is similar to the regression method except that for each missing value, it imputes a value randomly from a set of observed values whose predicted values are closest to the predicted value for the missing value from the simulated regression model …
