*Est.: the mean of estimators; CP: coverage probability, the proportion of the replicates that the 95% confidence interval covers the true value of estimate; Emp. SE: empirical standard error calculated as the sample standard deviation of the estimates over all replicates; Est. SE: the average of the standard errors over all replicates;—means the not available value.
