Is the suggestion to use the code in
https://github.com/apache/spark/pull/19638/files#r148852081 as the snippet
here? that seems to show a different adjusted R2 than what the test asserts
though. @tengpeng what's some R code that should execute given the code before
this snippet that produces the R2 / adjusted R2 values below?
