Fig. 2From: Identification and validation of an eight-lncRNA signature that predicts prognosis in patients with esophageal squamous cell carcinomaThe RMSE curves of the optimal gene combination based on RFE algorithm. The horizontal axis represents the number of lncRNAs variables, and the vertical axis represents cross-validation RMSEs. The marked place is the number of lncRNAs required to obtain the optimal valueBack to article page
