Hossein Falaki commented on SPARK-2515:
---------------------------------------
If we really have to implement another chi-square test method, I think
Likelihood-ratio test would be a good candidate.
On the return type:
* What is left for the Summary field? Why can't this be the toString method?
* I am not sure, but maybe this df is too cryptic for non-experts. How about
degreesOfFreedom?
