How can I do exponential regression in Javascript?

Question

can someone tell me how to do exponential regression or point me to a good explaination? I want to implement it in a javascript tool. I know that theoretically, I have to create a discrepancy function, take its first derivation, set it equal to zero and solve for the three parameters of the exponential function, but is there a simplified algorithm that allows me to do this without solving each time and so on?

Answer 1

I have little experience with exponential (nonlinear) regression, but it looks like there's a javascript tool here for demonstrating:

If you view source, you'll see the javascript behind that demo.
