[Retracted] Severity Assessment of COVID-19 Using a CT-Based Radiomics Model

Figure 6

ElasticNet algorithm for feature selection. The first (a) shows coefficient profiles along the full path of possible values for radiomic features. The MSE path (b) indicates that the dotted vertical line was plotted at the value selected using 10-fold cross-validation in (a). The coefficients in the ElasticNet model (c) resulted in 38 features based on selected optimal values.
