-----------------------------
Summary: Can you add some statistics to do logistic regression
better in mllib?
Key: SPARK-3195
URL: https://issues.apache.org/jira/browse/SPARK-3195
Project: Spark
Issue Type: New Feature
Components: MLlib
Affects Versions: 1.3.0
Reporter: miumiu
Fix For: 1.3.0
HI，
In logistic regression model practice，Test of regression coefficient and
whole model fitting are very important.Can you add some effective support on
these Aspects?
Such as,The likelihood ratio test or the wald test is offer used for test
of coefficient,and the Hosmer-Lemeshow test is used for evaluate the model
fitting.
Learning that we have ROC and Precision-Recall already,but can you also
provide KS statistic,which is mostly used in Model evaluation aspect?
