And you made two mistakes in two different posts just writing down
the formula for the REAL correlation matrix! :-)

"A Treatese on key MISSPELLINGS and inconsequential TYPOS".

Most typos are inconsequential, as the typo in the title above. But
when
someone (in that post) claims statistical expertise and then spells
several
times "statics" and "Stactics" for "statistics", they become key
misspelings
that betray the claim of the misspeller as an expert in statistics.

The same goes for your FOUR-TIME mistyping of the correlation
matrix formula,

There you go again. I mistyped the formula once. I cut and pasted it
another time. That's only TWICE. The formula contained V^(-1/2)
twice.

You need to slow down and get your 2s and 4s straight.

Greg, you're the one who corrected my TWO to FOUR (see above).

You are just a chronic excuse-making, know-nothing in statistics,
wasting everyone's time arguing the unarguable.

Give it a rest, and try to learn something form others, such as
Eric Bohlman in this case, if not from me.

Learn what? How to misrepresent the meanings of someone
else's posts? ... Spare me.

Learn what a correlation matrix is; and learn how not to twist facts.

P.S. At Sea, from Bangkok to Kuantan, Malaysia. I would have
responded
to this post sooner, had I known that my regular posting ID had been
barred
by Google (the same sabbotage by rec.travel.cruises posters in their
FALSE
"abuse report" <which two posters were caught boasting about in their
posts
the last time>. I had thought that the ISP of the cruiseship blocked
the use
of newsgroups until I got a tip from someone in this group who saw that
my
Large_Nassau_Grouper posting ID had been barred. So, as before, I'll
be
posting with the Dr_Bob account until I have time to deal with Google
about
the sabbotage. THANK YOU, the "Deep Throat" of sci.stat.math who
tipped
me off about the Google ban.

P.P.S. If anyone uses groups.google.com advanced search with "Reef
Fish"
as the author, Google will find ALL of my posts (under all posting IDs)
with
Reef Fish as the posting author name.
