A typical elimination. A typical elimination is shown based on the data for phylum Actinobacteria. Each dot in the figure indicates one iteration. The procedure starts on the left hand side, with the full model. After some iterations performance(P), which reflects the percentage of correctly classified samples, has increased, and reaches a maximum. Further elimination reduces performance, but only marginally. When elimination becomes too severe, the performance drops substantially. Finally, the selected model is found where we have the smallest model with performance not significantly worse than the maximum.
