data |
Training data of class |
dependent.variable.name |
Name of the dependent variable. For survival forests this is the time variable. |
formula |
Object of class formula or character describing the model to fit. Interaction terms supported only for numerical variables. (Formula interface not yet supported in varSelRanger). |
frac |
Fraction of top variables to drop after each iteration. |
min.vars |
Minimum number of variables allowed in a model. |
importance |
Variable importance mode. One of 'none', 'impurity', 'impurity_corrected', 'permutation'. The 'impurity' measure is the Gini index for classification, the variance of the responses for regression and the sum of test statistics (see splitrule) for survival. |
