OneR in Medical Research: Finding Leading Symptoms, Main Predictors and Cut-Off Points


We already had a lot of examples that make use of the OneR package (on CRAN), which can be found in the respective Category: OneR.

Here we will give you some concrete examples in the area of research on Type 2 Diabetes Mellitus (DM) to show that the package is especially well suited in the field of medical research, so read on!
