Fig. 2: Model performance (RMSE, log scale) of the best four-parameter model (Amirian) compared to all other models (indicated in the header for each panel).
Each point corresponds to a separate PI curve. Point color corresponds to the difference in R2adj between Amirian model and the comparison model. The 1:1 line is shown as a black dotted line. Models are defined in Table 1, and p in each panel indicates the number of parameters in the corresponding model.
