It'd be nice to be able to fit GLMs without covariates. It's usually trivial, except when offsets are involved...

What should the interface look like? fit is pretty straightforward, but I'm not sure about predict.

I found a way to phrase the obvious, which worked for me using the formula interface:
formula = "Y~ {np.ones_like(Y)}", fit_intercept=True

The more obvious approach "Y~1" throws errors with "fit_intercept=True" and with "fit_intercept=False"
