Figure 3 Radiomic feature selection using least absolute shrink-age and selection operator logistic regression. A: Selection of tuning parameters (l) in the least absolute shrink-age and selection operator model used 10-fold cross-validation via minimum criteria. The area under the curve was plotted vs log (λ). Dotted vertical lines were drawn at the optimal values using the minimum criteria and the 1 standard error of the minimum criteria (the 1 - standard error criteria); B: Least absolute shrink-age and selection operator coefficient profiles of the radiomic features. A vertical line was plotted at the optimal λ value, which resulted in five features with nonzero coefficients.
