Notes: MM (missingness mechanism), TV (true value), CD (case deletion), SE (standard error), CR (coverage rate), AW (average width of confidence intervals), RMSE (root-mean-square error). CR and AW are based on 95% nominal confidence rate. CD(SE) column contains AUC estimate and estimate of its standard error under case deletion.
