Fig. 1From: Mechanism-aware imputation: a two-step approach in handling missing values in metabolomicsFlow-diagram of our proposed two-step, Mechanism Aware Imputation (MAI) algorithm. The red box corresponds to Step 1 of MAI for classifying the underlying missing mechanisms. The blue box corresponds to Step 2 of MAI for imputing missing values based on the type of missing mechanism as predicted in Step 1Back to article page
