%description
An introduction to several novel predictive variable selection methods for
random forest. They are based on various variable importance methods
(i.e., averaged variable importance (AVI), and knowledge informed AVI
(i.e., KIAVI, and KIAVI2)) and predictive accuracy in stepwise algorithms.
For details of the variable selection methods, please see: Li, J.,
Siwabessy, J., Huang, Z. and Nichol, S. (2019)
