Simulation results for ŜD of the conditional bivariate survival function where a = (.05, .05), Est and BSE are averages of the estimate and bootstrap standard error of ŜD, ESE is the empirical standard error of the estimator and Cov is the empirical coverage of a .95 Wald confidence interval based on the BSE.
