Table 1 Performance measures and their formulas used in the simulation study
From: Bayesian network-based missing mechanism identification (BN-MMI) method in medical research
Performance measure | Formula |
|---|---|
Validity of the BN-MMI method | (the number of times when the estimated missing data structure completely coincides with the real one)/(the total number of simulations) |
Validity of the logistic regression method | (the number of times when the estimated missing data structure coincides with the real one in terms of the relations between missing indicator variable and other variables)/ (the total number of simulations) |
Simulation consistency for the relation between variable A and B | (the number of times when the estimated relation between variable A and B is true) /(the total number of simulations) |
Robustness | \(\frac{{\sum }_{i=1}^{N}{\left(validit{y}_{i}-\overline{validity}\right)}^{2}}{\left(N-1\right)}\), where N is the total number of simulations, and i refers to the i-th simulation |
