Eight key long non-coding RNAs predict hepatitis virus positive hepatocellular carcinoma as prognostic targets

Figure 3 Plots of regression coefficient based on least absolute shrinkage and selection operator regression. A: Least absolute shrinkage and selection operator (LASSO) coefficient profiles of the fractions of the 406 significant long non-coding RNAs (lncRNAs) in univariate Cox regression analysis. The solid vertical line implies the optimal lambda value determined by cross-validation; B: Cross-validation for tuning parameter selection in the LASSO model. The vertical lines are drawn at the optimal values by minimum criteria and 1-standard error criteria. And the solid vertical line represents that eight lncRNAs were finally determined.
