Note: Bootstrap results are based on 5000 samples.***, **, and * denote significance at 1%, 5% and 10% levels (2-tailed). Figures in boldface denote the unstandardized coefficients (beta). Figures in italics denote the estimated bias. Figures in parentheses (·) denote robust standard errors and [·] denote BCa 95% confidence intervals.
