Fig. 4From: Predicting COVID-19 mortality risk in Toronto, Canada: a comparison of tree-based and regression-based machine learning methodsDensity plots of the predicted mortality probability based on a random sample of the 200 repeated split samples. The distributions of the predictive mortality probability are highly right-skewed, so the predicted probabilities below 0.2 are suppressed for better visualization of the higher predictive riskBack to article page
