Construction of the 10-lncRNA-based classifier. (A) Ten-time cross-validation for tuning parameter selection in the LASSO model. The solid vertical lines are partial likelihood deviance ± standard error (SE). The dotted vertical lines are drawn at the optimal values by minimum criteria and 1-SE criteria. A λ value of 0.187 with log(λ) = −1.678 was chosen by 10-time cross-validation via 1-SE criteria. (B) LASSO coefficient profiles of the 176 glioma-prognosis-associated lncRNAs. A dotted vertical line is drawn at the value identified by 10-fold cross-validation.
