BIC, Bayesian information criterion; Model 1 is the first-order Legendre polynomial random regression model; Model 2 is the second-order Legendre polynomial random regression model; Temp, daily average temperature (°C); RH, daily average relative humidity (%); THI, daily average values of temperature – humidity index (°C); N.C., not converged. The values in bold indicate the largest coefficient of determination or smallest Bayesian information criterion value obtained for each trait.
