Part I shows mean, mean after bias correction, mean of the bootstrap standard error, non-coverage percentage of 95% BCa bootstrap confidence intervals (with left and right non-coverage percentages), and mean length of the interval. Part II shows, for pgs ≤ 0.3, the same type of results as part I, but for Inline graphic truncated at zero. Instead of means, medians are given. At pgs = 0.0, only non-coverage at the right of pgs = 0.0 is considered
