Comparison of open-source random forest to IHME random forest. The IHME random forest was tested on a set of IHME hospital-based data, both with and without health care experience (HCE) variables. HCE variables are binary questions on previous medically diagnosed conditions (including high blood pressure, tuberculosis, cancer), and details transcribed from the respondents’ medical records. Our IHME subset contained some, but not all, HCE variables. The ORF performance was similar to the IHME random forest method on the full hospital-based dataset without HCE variables, but performed less well when HCE variables were included [12]. HCE, health care experience; IHME, Institute for Health Metrics and Evaluation; ORF, open-source random forest.
