%description
The Explainable Ensemble Trees 'e2tree' approach has been proposed by Aria
et al. (2024) <doi:10.1007/s00180-022-01312-6>. It aims to explain and
interpret decision tree ensemble models using a single tree-like
structure. 'e2tree' is a new way of explaining an ensemble tree trained
through 'randomForest' or 'xgboost' packages.
