Details

• For example, you can choose to remove a protein from the model_df object if the protein does not show distinct patterns of variation among conditions. This protein may show mostly overlapping distributions in the feature plots.

• Another incidence would be removing a protein that is very low in variable importance in the models built using train_models. You can visualize variable importance using varimp_plot.
