Of course! Thank you, Nick and Maarten!

Maarten, I was looking up your presentation on zoib as I received your
email. Does stata have LM specification tests for fractional logit?
The documentation doesn't seem to indicate it. A quick look at the
zoib help also doesn't reveal LM specification tests for that
procedure either. Is that correct?
