[英]is p-value deprecated in h2o glm
Elasticnet中是否棄用了p值? 以下參考資料顯示了系數中的p值http://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/glm.html
但是當我執行以下命令時我看不到p值
head(elastic_net_best_model@model$coefficients_table)
Coefficients: glm coefficients
names coefficients standardized_coefficients
僅當將compute_p_values設置為true時,才會計算p值,並且這僅在沒有正則化的情況下才有效,這需要lambda = 0
舉個例子,
library(h2o)
h2o.init()
x<-as.h2o(iris)
xg<-h2o.glm(y="Sepal.Length",training_frame=x,compute_p_values=TRUE,lambda=0)
head(xg@model$coefficients_table)
這給出了輸出:
