Table 3a shows the model selection and the coefficients of the final model. Df, Degrees of freedom; RSS, Residual Sum of Squares; AIC, Akaike Information Criterion; and Std. Error, standard error. Table 3b shows the adjusted R² (R²_adj), AIC, reduction of error (RE), and coefficient of efficiency (CE) values for the split-period calibration and verification.
