  "Description": "An introduction to several novel predictive variable\nselection methods for random forest. They are based on various\nvariable importance methods (i.e., averaged variable importance\n(AVI), and knowledge informed AVI (i.e., KIAVI, and KIAVI2))\nand predictive accuracy in stepwise algorithms.
