The least absolute shrinkage and selection operation (Lasso) method yields a model with sets of mass-spectral features for distinguishing between basal cell carcinoma (BCC) and normal skin. The average mass spectra calculated from raw peak abundances in all pixels of the training dataset are shown in red for BCC and green for normal.
