RF. We simply acknowledge that the standard variant with default values is widely used and conjecture that things will probably not dramatically change in the short term. That is why we made the choice to consider RF with default values as implemented in the very widely used package randomForest—while admitting that, if time and competence are available, more sophisticated strategies may often be preferable. As an outlook, we also consider RF with parameters tuned using the recent package tuneRanger [4] in a small additional study.
