在elasticnet中是否弃用了p值?以下参考显示系数中的p值 http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/glm.html
但是当我执行下面的命令
时,我没有看到p值 head(elastic_net_best_model@model$coefficients_table)
Coefficients: glm coefficients
names coefficients standardized_coefficients
答案 0 :(得分:3)
举个例子,
library(h2o)
h2o.init()
x<-as.h2o(iris)
xg<-h2o.glm(y="Sepal.Length",training_frame=x,compute_p_values=TRUE,lambda=0)
head(xg@model$coefficients_table)
这给出了输出:
