$\text{Bias}=\frac{1}{H}{\sum }_h^H(\widehat{{\theta }_h}-\text{true}\hspace{0.17em}\theta )$, where H = total number of Monte Carlo replications, $\widehat{{\theta }_h}$ = estimate of θ from the hth Monte Carlo replications, true θ = true value of a parameter; $\text{RMSE}=\sqrt{\frac{1}{H}{\sum }_{h=1}^H{(\widehat{{\theta }_h}-\text{true}\hspace{0.17em}\theta )}^2}$; SD = standard deviation of $\widehat{\theta }$ across Monte Carlo runs; DSE = deviance of average standard error estimate across Monte Carlo runs from SD; DSEfull = difference between average standard error estimate with missing data under each method and average standard error estimate with full data; Power/type I error = 1 – the proportion of 95% confidence intervals (CIs) that contain 0 across the Monte Carlo replications; Coverage = the proportion of 95% confidence intervals (CIs) that contain true θ across the Monte Carlo replications.
