Randomised trial of two treatment regimens for lung cancer.

COSSO is the short term for COmponent Selection and
        Smoothing Operator. The new regularization method automatically
        estimates and selects important function components by a
        soft-thresholding penalty in the context of smoothing spline
        ANOVA models.
