Frank McQuillan commented on MADLIB-1344:
-----------------------------------------
There is Pearson correlation
http://madlib.apache.org/docs/latest/group__grp__correlation.html
but not Spearman for ordinal variables.
It would be a good addition to add Spearman.
> Does Madlib support Spearman Correlation?
