Average apparent and cross-validated (CV) estimates for the AUC using T, Z information ( ${\text{AUC}}_{t_0,\tau }^{(2)}$) and Z information only ( ${\text{AUC}}_{t_0,\tau }^{(1)}$) with corresponding empirical SEs (ESE), average of the SE estimates from the perturbation-resampling method (ASE) for the apparent estimates and empirical coverage levels (Cvg) from setting (i), the low event rate setting and (ii), the moderate event rate setting. All entries are multiplied by 100.
