Figure 6.

The distribution of degree of informativeness of Z in L-PLS and comparison of complexity of the models, number of variables and RMSE. Results for the phenotype ‘Melibiose 2% Rate’ are presented for three models, M1 (2-stage stepwise variable elimination in L-PLS), M2 (stepwise variable elimination in PLS) and M3 (St-PLS). In the upper left panel (a), the information content of the background information (Z) in M1 is presented. Comparison of number of used PLS components in the upper right panel (b), the number of selected variables in the lower left panel (c), RMSE on training data in the lower center panel (d), RMSE on test data in the lower right panel (e) for each model is presented.
