-oglm- was inspired by SPSS's PLUM command and its results have

I think it's worth noting here that PLUM was originally a program
written by Peter McCullagh, whose 1980 paper (Regression Models for
Ordinal Data, JRSS, B 42, 109-142) laid out much of the foundation
for ordinal regression models. I have no idea how SPSS came by this,
or whether their implementation bears any resemblance to the original.
