The returned vector imp has one element for each input variable in the data used to train this tree. At each node, the risk is estimated as node impurity if impurity was used to split nodes and node error otherwise. This risk is weighted by the node probability. Variable importance associated with this split is computed as the difference between the risk for the parent node and the total risk for the two children. 希望有強者可以告訴我這段文字的意思... 不知道在這邊可不可以問這種類型的問題耶... 如果不行請告訴我我會自D的... 如果不行的話請各位版友順便跟我說那裡可以PO這種文喔～感謝大家的幫忙謝謝感激不盡 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.44.99.123
