The robust standard errors are in parentheses in Model 1, and the statistic for measuring goodness-of-fit is R2. The bootstrap standard errors are in parentheses in Models 2–6, with a sample size of 100, and the statistic for measuring goodness-of-fit is Pseudo R2. * p < 0.1, ** p < 0.05, *** p < 0.01.
