S.E., standard error; CI, confidence interval; CLT, central limit theorem; HC, heteroscedastic consistent method; percBS, percentile bootstrap; BCa, bias corrected and accelerated bootstrap. Estimates are in the direction of male percentages minus female percentages. Winsorized and trimmed means pertain to modifying about 20% of the tail distributions; 20.43% for Example 1 and 20.51% for Example 2.
