Had us in splits, did Prof Bob Stine... "We are genetically programmed to see patterns in random data. The gene that couldn't distinguish between bushes with a stealthy tiger and just bushes walked into the bushes... and never came back."
He of course went on to make statistical sense about how after the linear regression finishes relating the dependent (response) variable to the independent (predictor), what's left (the residual plot) may still have a pattern that only a human eye can discern, which then signals that the time's come for a data transformation. Greek? Not quite... when Bob teaches. Bye Bob! There's at least one guy in our section that you've really transformed... not me, S.
