Good day,
I've got an array of data to which I'm trying to fit to the model y = A*sqrt(x-x.0), basically the upper half of a parabola crossing at an arbitrary x-coordinate. I'd be using A and x.0 as the fit parameters. What's the best way to define this sort of model? It's not a standard one as far as my (limited) experience goes.
Thanks for your suggestions!
