英文:
Variable Importance P-Values
问题
importance_pvalues（https://rdrr.io/cran/ranger/man/importance_pvalues.html）命令是否可以通过mlr3使用？换句话说，我是否可以指示在调用学习器时输出p值？如果不能，我该如何提取ranger对象以用作importance_pvalues命令的输入？
英文:
Can the importance_pvalues (https://rdrr.io/cran/ranger/man/importance_pvalues.html) command be used via mlr3? In other words, can I indicate that I would like the p-values outputted in my call to the learner? If not, how would I go about extracting the ranger object to use as input for the importance_pvalues command?

你可以始终通过 mlr3 中的 $model 字段访问存储的模型。
library(mlr3verse)
library(ranger)
learner = lrn("classif.ranger", importance = "impurity_corrected")
learner$train(tsk("sonar"))
importance_pvalues(learner$model)
英文:
You can always access the stored model via the $model field in mlr3.
library(mlr3verse)
library(ranger)
learner = lrn("classif.ranger", importance = "impurity_corrected")
learner$train(tsk("sonar"))
importance_pvalues(learner$model)
