[R] Test of Parallel Regression Assumption in R

[Bert Gunter]

Heather:

You are at Vanderbilt, whose statistics department under Frank Harrell
is a veritable bastion of R and statistical wisdom. I strongly
recommend that you take a stroll over there in the lovely spring
weather and seek their help. I can't imagine how you could do better
than that!

Cheers,
Bert
