in reply to quadratic and exponential regression

A long time ago, I used a Texas Instruments SR-50A to do linear regression in high school. This calculator had a single memory location, and the manual explained the procedure. Good times.

So, if you're trying to do exponential regression, how about just doing linear regression on x, log( f( x ) ) values? You can convert that back into an exponential afterwards.

That's what I'd try.
