Figure 2 Least absolute shrinkage and selection operator regression analysis for variable selection. A: Least absolute shrinkage and selection operator (LASSO) coefficient profiles of the candidate variables; B: Ten-fold cross-validation for tuning parameter selection in the LASSO model. The dotted vertical lines represent the log(λ) values corresponding to the minimum mean squared error (lambda.min) and the one standard error criterion (lambda.1se).
