The following is an exchange between myself and bill chambers from
October of 1997 in the forum sci.stat.consult. I post it here to point
out to relatively new readers of this list that Chambers has been doing
his insulting and circular reasoning on internet stats groups and lists
for a *long* time.
I recovered the post using Dejanews.

Mr. Chambers,
I have not made any insults of you or your method. I have simply pointed
out that you need to evaluate the
suitability of this forum for your discussion. If you think I've
insulted you, you need to quote the insult (answer in
public, on this forum) or retract your accusations against me (answer in
public, on this forum)

Correct, I have not read your earlier explanation of this unusual
terminology. I don't read every post that comes
from Stat-L. And I have unsubscribed at times off and on for the last 2
years so I may have not even seen your
previous writings on this matter. But if you insist on catisgating
someone for trying to engage in bonafide
discourse with you, so be it. I wouldn't want you to be uncomfortable in
this discussion.
Again you insinuate negative valence regarding Georgia Tech... why? What
axe do you have to grind against that
institution? Why does Georgia Tech matter to you? (You failed to answer
that question from my previous post.)
(Answer this by email, since this is a forum for discussion of
Statistics.)

I see, I'll look at this. But my first thought is this is a natural
consequence of arbitrarily dividing the scatterplot in
the way you suggest. So, I'll trust that it is true (others can jump in
if my trust is misplaced). Why does it matter?
Don't jump ahead, what is the next consequence?
Please, explain it to me. Be patient because I want to understand.

Egad! The honor of Georgia Tech is not defended by me. You can hand me
that sword but I don't have to pick it
up. The honor of Georgia Tech is defended by many others of much greater
capability than myself.
Also, I have never claimed a massive intellect in this forum. Where does
that statement come from? Do you assume
I have a massive intellect? Thanks!, but I don't really think so. Please
indicate, via email (not on this forum since it
is for stats discussion), where I've said something that leads you to
think so.
Finally, I ask this in all seriousness, is it *necessary* for you to
insult others when you converse with them? ("learn
to behave so badly...") What need are you satisfying?
