“变量重要性图”对每个 X 变量的 VIP 值绘图。“变量重要性表”显示 VIP 得分。VIP 得分用于衡量变量在 X 和 Y 建模中的重要性。若变量有小的系数和小的 VIP,则它是要从模型中删除的候选项 (Wold 1994)。值为 0.8 通常视为小的 VIP (Eriksson et al.

However, most of these methods produce algebraically ...
Through permutation of the OOB data, and within the imputation loop, we could obtain the scaled average variable importance of the different predictor variables. Figure2shows the resulting variable importance plot for the top-30 predictor variables. The use of multiple imputation allowed in addition ...
It is also used to get estimates of variable importance. RF for feature selection uses backward variable elimination approach, which is the wrapper approach, with the OOB error as a minimization criterion. The backward elimination begins with all the features in the model and at each step ...
Note that the ordering of variables in the plot is arbitrary. Full size image We find that the pattern of the coefficients induced in the data generating process is not reflected by the importance values computed with the ordinary permutation scheme. With this scheme the importance scores of the...
