a GECROS-model parameters and their units are defined
in Table 4;
b \(\sigma_{1}\), \(\xi\) and \(\lambda\) denote the
heteroscedasticity parameter, the skewness parameter and the Box-Cox
transformation parameter in the error model, respectively (see the
text). Definition of the traits used in the subscript of symbols:W above, aboveground biomass;
W grain, grain weight; W leaf,
leaf weight; N above, aboveground N content;
N grain, grain N content; N leaf,
leaf N content in the canopy; and LAI, leaf area index.
