model.estimate_effect and model.refute_astimate throws 'A column-vector y was passed ...' error #1212

Hi team,

when I use above mentioned methods I get the the following message:

"A column-vector y was passed when a 1d array was expected. Please change the shape of y to (n_samples, ), for example using ravel()."

How can I avoid this? Is this a bug or am I doing something wrong?

Thanks
