Model formulae in XLISP-Stat
This is the current version of a model formula system for XLISP-Stat.
Feel free to take it and play with it: formal details in the file COPYING
It isn't finished yet and I don't expect that it's bug-free. Take care.

In addition to a basic model formula object there are some methods that extend regression-model-proto to use the model formulae. My GEE code will accept either model formulae or design matrices transparently.
