Validate the outcome against the family support, then fit.

Parameters:

• X (DataArray) – Input features as an xarray DataArray.

• y (DataArray) – Target variable as an xarray DataArray. Bernoulli outcomes must be 0/1; Poisson and Negative Binomial outcomes must be finite, non-negative, and integer-valued.
