Assessment of the elastic net model for virus incubation time prediction. a A scatter plot of the incubation periods of the CoV training set compared to the model predictions, with the model R² in the upper left corner. b A scatter plot of the incubation periods of the test set compared to the model predictions. The box in the bottom right corner contains Spearman’s ρ between the predictions and the true values, the p value of the Spearman’s ρ, the model R², and the mean absolute error (MAE). c A heatmap of the coefficients of each feature using different training sets. d A bar plot of the model performance metrics using different subsets of training and testing data, with the number of samples in the testing data for each subset indicated. e A scatter plot of the incubation periods of the test set compared to the model predictions when SARS-CoV-2 is left out of training. The box in the top left corner shows the model’s performance metrics
