Description

Recursive Feature Elimination; First, the algorithm fits the model to all predictors. Each predictor is ranked using it’s importance to the model. Let S be a sequence of ordered numbers which are candidate values for the number of predictors to retain (S1 > S2, …). At each iteration of feature selection, the Si top ranked predictors are retained, the model is refit and performance is assessed. The value of Si with the best performance is determined and the top Si predictors are used to fit the final model.

Arguments

cpm

Matrix; Matrix containing cpm values.

classes

Character; classifications corresponding to the cpm columns.

nCV

Integer; Number of cross-fold validations.

s

Numeric; Vector indicating the number of features to select in each testing round.
