From: Comparison of four light-response models using relative curvature measures of nonlinearity
Assessment of nonlinear behavior of individual parameter of the four photosynthetic light response models (A EM; B RHM; C NHM; D MRHM) for 42 datasets. G indicates good close-to-linear behavior (the absolute value of corresponding skewness |Sk| ≤ 0.2); M indicates a moderate close-to-linear behavior (0.2 < |Sk| ≤ 0.5); and B indicates bad close-to-linear behavior (|Sk| > 0.5). The numeric values in percentage represent the proportions of G (or M, B) among 42 datasets for each parameter. For example, 40.48% in panel (A) represents the proportion of G scores for parameter a in EM is 40.48% among 42 datasets.
