Good data regression sites?
In the past, I always used zunzun.com, but it seems to be down.
My problem: I have z is a function of x and y. I want to do a polynomial data regression to determine the best fit, where
z = a + bx + cy + dxx + eyy + fxy
This was super easy on zunzun. Copy my 700 or so data points, pick the error method, and zoom! out go the constants.
Are there any other good sites for online regression analysis?
