Table 4 Average LRMSE values for each data set using the gold standard optimal imputation method, the STS selected method, and the EBS selected method for the "first tier" simulations in Simulation III. The difference in LRMSE values between the two selection schemes and the optimal method are also indicated, with an asterisk indicating a p-value below 0.05.
