Jerry -

Yes, CORREL has not changed.

After further recollection and investigation, I realize that my faulty
recall was related only to differences in COVAR and the Analysis ToolPak's
Covariance tool.

Second, as I recall, depending on the version of Excel, there may or may
not be an adjustment for the number of observations (degrees of freedom),
but maybe that was only for COVAR.

I do not recall that. As best I recall, CORREL has used a numerically
stable 2-pass algorithm in all versions, where RSQ and PEARSON only
switched to that in 2003. Prior to 2003, the R-squared value from LINEST
was wrong if no intercept was fit.
