Whether the two variables have the same units does not matter. Moreover, even if there were some way of converting cm to kg the correlation would still be the same because the correlation is invariant under unit conversion as it is invariant under multiplication of its arguments by a constant. As for your second question, the correlation estimator is a continuous function of each of the

Also, I'd be happy to email a dataset that exhibits this behavior if anyone is curious enough. Cheers, A. -- Allan Strand, Biology http://linum.cofc.edu College of Charleston Ph.
