Peng Meng commented on SPARK-20764:
-----------------------------------
Thanks [~yanboliang], is that check too short?
For the PySpark LinearRegressionSummary test. There is only two lines of code,
just check one function.
If there is a typo, suppose I write [return
self._call_java("degreeOfFreedom")] (degreeOfFreedom to replace
degreesOfFreedom)
There will not return any error, and pass all test. But this certainly doesn't
work.
> Fix visibility discrepancy with numInstances and degreesOfFreedom in LR and
> GLR - Python version
