Summary statistics for the predictive model of H index with aridity, temperature seasonality (TS) and weight percentage of clay particles (WPC) as proposed by the best subset regression. All predictor variables were log10-transformed. The adjusted R2 (total variance explained by each model), the P-value, Akaike’s Information Criterion (AIC), the estimate (Est.), the significance (P), the Bonferroni-corrected P-values (PBon), as well as the relative importance (rw) of each significant predictor of the best subset regression are reported.
