http://www.alglib.net/interpolation/leastsquares.php Curve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. Curve fitting can involve either interpolation, where an exact fit to the data is required, or smoothing, in which a "smooth" function is constructed that … See more Most commonly, one fits a function of the form y=f(x). Fitting lines and polynomial functions to data points The first degree polynomial equation See more If a function of the form $${\displaystyle y=f(x)}$$ cannot be postulated, one can still try to fit a plane curve.
