Z_imp and Z_real are the test statistics (Z-score) obtained from the imputed and original datasets, respectively. The last column is the difference between the imputed test statistics and the analytical test statistics.

^aThe real test data is obtained from the NFBC data by removing the 500 individuals who are assumed to be missing in our experiment.
