Hmm interesting issue. Will check it out.

Works. Go ahead.

Are there any particular cases in statsample that are not covered in statsample-glm? If no, then you can safely remove linear regression from statsample and not re-implement the formula language...

Yes @lokeshh is working on it as part of his GSOC project.

We've also factored the dataset/vector into a separate gem. I think the next step would be to design an integrated API for statsample.

The patch will involve replacing `n_valid` with `count_values`. If you could patch it and send a PR, I can merge it into the main branch.

Gem has been updated and is awaiting release by @agarie . In the meanwhile you can clone from the github repo and use it. There should be no errors this...

Currently Probit is implemented only using MLE. Implementation using IRLS would also be helpful.

Sure! YARD would be the way to go.

What do you suggest should be done? Let's first profile the code and see the slowest places. Then we can optimize these and see if we should write C extensions...
