Estimated versus true CSMFs for 500 Dirichlet splits, showing that for selected causes of adult mortality (AIDS, colorectal cancer, maternal, and IHD), the performance of RF varies. For AIDS and IHD, RF tends to overestimate the cause fraction when the true CSMF is small and underestimate otherwise. For colorectal cancer, RF mostly assigns the same CSMF regardless of true CSMF, and for maternal causes, RF is more accurate.
