Alex, Thanks for getting back. Sorry for my lack of knowledge. What does IIUC stand for? The code I'm trying to port uses fmgmdist exclusively and tries anywhere from 1 to 5 components, and then choose the best component by selecting the lowest AIC value from the 5 tries as documented here: ht

I'll let someone familiar with that code base opine 😉 Gary On Mon, Mar 11, 2024, 2:48 PM Craig Brautigam wrote: > Gary, > Gary is this something you would agree is an issue? I don't want to go > through the effort of putting an official issue out there if it's something > I'm misunderstanding.

Hi Craig, In general, the fastest way to address an issue you care about is to provide a PR in GitHub, with a unit test 😉 Gary On Mon, Mar 11, 2024, 2:06 PM Craig Brautigam wrote: > Just bumping this up...Would it be possible to get a fix for this? > > > Thx! > > > ___
