Additional information on the variables may be found in Table 1. Each model is subjected to a quantitative regression control to account for peripheral and temporal effects. Although a fixed term is included, it is omitted. Typical bootstrap mistakes (100 duplicates) are listed in brackets. Q25 denotes the twenty − fifth percentile, Q50 denotes the fifty − fifth (middle) percentile, and Q75 denotes the seventieth percentile. The asterisks indicate the following degrees of significance: **p0.05; ***p0.01; *p0.1. Author’s calculation
