I don't know what your first language is.

Does it really matter?

If you read what I wrote, I meant
that I studied these methodologies also 30 years ago, and therefore I was
suggesting that I might be out-of-date.

English is one of the most ambiguous language among all languages.
What
you meant about you "might be out of date" can also be interpreted to
be an excuse for having forgotten whatever little you knew 30 years
ago.

The fact that you say that methods haven't changed since then - when I had
some knowledge about them - gives me more credence to what I say.

Maybe you can give us the benefit of your wisdom ie by a reference to your
book - otherwise you remain hidden by an enigmatic alias.

I didn't say my "book". I said my doctoral dissertation, titled
"Cluster Analysis" which is unpublished but anyone can find it in
microfiche form in the standard dissertation sources.

The book that we all used to swear by was "Cluster Analysis" by Brian
Everitt (Wiley, 1993).

Then you are GROSSLY deficient in your knowledge about the content
and SCOPE of "cluster analysis". Everitt is a new comer in the
clustering field. He wrote some good books, but if one were to name
the top 10 books on cluster analysis or numerical texonomy, his book
would not be on that list.

You swear by that book, and you'll have plenty of classification
experts swearing at you. :-)
