Table 4.

Empirical rejection rates and powers of two-sample tests under the incorrect imputation model; The null hypothesis scenario corresponds to the first column (I vs. II). The second and third columns (I vs. III and I vs. IV) indicate powers. Configuration I is the generation model for group 1 (Z = 1), which is fixed, and configurations II, III, and IV correspond to the generation models for group 2 (Z = 0).
