Chuck, Thank you. I need to make some time to understand the B-splines to use them appropriately. Unfortunately, my mathematical statistics learning was many years in the past ... but we had moved ahead of writing on clay tablets by that time. Not needing to retain that knowledge for many years means it was replaced by more pressing current knowledge. The B-splines do look promising, though. Rich -- Richard B.
