WebData fitting is the process of fitting models to data and analyzing the accuracy of the fit. Engineers and scientists use data fitting techniques, including mathematical equations … For linear-algebraic analysis of data, "fitting" usually means trying to find the curve that minimizes the vertical ( y -axis) displacement of a point from the curve (e.g., ordinary least squares ). See more 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 … See more If a function of the form $${\displaystyle y=f(x)}$$ cannot be postulated, one can still try to fit a plane curve.
