That would be great!
I really do think that the scikits learn and statsmodels must talk
together now that learn has had a release as well ( I don't recall
seeing it mentioned hint hint!). What would be nice is the acceptance of
input data types between learn and statsmodels especially for things
like logistic regression. While I understand the need for duplicate
functions, it may be desirable share at least code since both code bases
are still relatively 'new'.
