Predict multicategory causes of death in lung cancer patients using clinicopathologic factors

Random forests (RF) is a widely used machine-learning algorithm, and outperforms many other machine learning algorithms in prediction-accuracy. But it is rarely used for predicting causes of death (COD) in cancer patients. On the other hand, multicategory COD are difficult to classify in lung cancer patients, largely because they have multiple labels (versus binary labels).We tuned RF algorithms to classify 5-category COD among the lung cancer...
