I have the parameter estimate CI's and can do it easily for when a variable has only 2 levels, but am unsure of the formula when there are 3 or more.

Thanks

Two-level nominal effects are coded 1 and -1 for the first and second levels, so

This seems to point in the same direction ... If you're still concerned, I'd suggest contacting JMP support and letting us know what they say.

Thank you for the nudge in the right direction. It makes sense now.

I do wish they'd bring back OR CI's though. :)
