Variable Selection Using Random Forests R package, implementing a three steps variable selection procedure based on random forests. Initially developed to handle high dimensional data (for which number of variables largely exceeds number of observations), the package is very versatile and can treat most...

Zhang and Hamori (2020) rely on random forests, logistic regression, support vector machines, and extreme gradient boosting (XGBoost) to predict crude oil price crashes. We complement their work by providing a hybrid perspective of machine learning. Furthermore, we provide valuable insights regarding...

Recently, the variable importance measures yielded by random forests have also been suggested for the selection of relevant predictor variables in the analysis of microarray data, DNA sequencing and other applications [2–5]. Identifying relevant predictor variables, rather than only predicting the ...

In random forests, another source of diversity is introduced when the set of predictor variables to select from is randomly restricted in each split, producing even more diverse trees. In addition to the smoothing of hard decision boundaries, the random selection of splitting variables in random fo...
This support can work with existing sklearn model selection classes such as LassoCV or GridSearchCV, or you can pass a list of models to choose the best from among them when cross-fitting. from econml.dml import LinearDML from sklearn import clone from sklearn.ensemble import RandomForest...
