alcohol correlation... [message #22660]

I am sure someone else must have noticed this in the IDL 5.3 help file on
"Correlation Analysis." Here is a quote:

"Although a high degree of correlation (a value close to +1 or
-1) indicates a good mathematical fit to a linear model, its applied
interpretation may be completely nonsensical. For example, there may be a
high degree of correlation between the number of scientists using IDL to
study atmospheric phenomena and the consumption of alcohol in Russia, but
the two events are clearly unrelated."

While I am not Russian, I can claim that my alcohol consumption has
increased since I began using IDL to study atmospheric phenomena 3 months
ago... is there a possible correlation here after all?
