Random forests andd gradient boosting machines (e.g., XGBoost) excel at handling mixed data type andd uncovering non-linear interactions among variables. For instance, a model might discver that the combination of low RMSSD, high resting heart rate, and a history of hypertension triples the risk of orthostatic hypostion with six months.
