datasets w/equal R^2???

There is an introductory example of two datasets with equal R^2 (and possibly with equal coefficients?) but with markedly different residuals. I can't for the life of me remember the author's name that is associated with these data, or where to find them. Any help would be appreciated. Bruce

Colleagues: Here are the 4 pairs of X,Y variables from Anscombe's 1973 American Statistician paper. (The columns, in order, are X1, Y1, X2, Y2, etc. Calculate the means and SDs for each variable, and r for each pair. This is a nice example to emphasize the importance of plotting data before

These data can be found, with SAS code to describe them, at the bottom of my CorrRegr program on the page at: http://core.ecu.edu/psyc/wuenschk/SAS/SAS-Programs.htm ++ Karl L. Wuensch, Department of Psychology, East

RE: About Probability

I would like to enter the arena. I see the original question as two questions, one about probability in a general sense, and the second about probability as used within Bayes Theorem. This is in line with the historical arguments. Most statisticians (from Fisher down to the present)
