Fig. 3 Feature selection using LASSO regression model(A).
Tuning parameter selection by 10-fold cross-validation via minimum
criteria. Partial likelihood deviance was plotted versus log(λ)(B).
Coefficient profile of characteristics associated with recurrence of
patients. Vertical line is shown at the optimal value with four nonzero
coefficients.
