Means of estimated MSE values from the simulation study. MSE “Apparent” was the performance on the original data. MSE “Corrected” = MSE apparent - Optimism internal MSE “External” was the performance on an independent new data with no missing values MSE “Appr 1”, “Appr 2”, “Appr 3” and “Appr 4” were based on subtracting the value of optimism estimated via the four approaches of handling missing data from MSE apparent (with missing data).
