Texture feature selection using LASSO Cox regression. a Selection of tuning parameter (λ) in the LASSO model using 10-foldncross-validation with minimum criteria. Partial likelihood deviance was plotted versus log (λ). Vertical line of the optimal values (log (λ) = − 2.573) were drawn based on the minimum criteria and the 1-standard error of the minimum criteria. b LASSO coefficient profiles of 36 texture features. Vertical line was plotted at the selected value via 10-fold cross-validation, where optimal λ resulted in 3 nonzero coefficients
