[SI-LIST] Re: DesignCon quote

Here's a reference to an even older citation, which I can't now check:

"[George] Box used it as a heading in a book chapter in 1979. Here is =
the
citation:

Box, G.E.P., Robustness in the strategy of scientific model building, in
Robustness in Statistics, R.L. Launer and G.N. Wilkinson, Editors. 1979,
Academic Press: New York."

I found a slightly different citation on WikiQuote, which suggests =
George
Box and Norman Draper had two phrasings in their book Empirical
Model-Building and Response Surfaces (Wiley 1987):

        "Remember that all models are wrong; the practical question is how=20
        wrong do they have to be to not be useful."

        "Essentially, all models are wrong, but some are useful."

I don't have a copy of this book to confirm the citation, but it seems =
like
most folks cite Box as the originator of the quote in this general =
timeframe
(late-80's).

Wherever it came from, I like it...
