WebAug 9, 2024 · Fitting a set of data points in the x y plane to an ellipse is a suprisingly common problem in image recognition and analysis. In principle, the problem is one that is open to a linear least squares solution, since the general equation of any conic section can be written. F ( x, y) = a x 2 + b x y + c y 2 + d x + e y + f = 0, WebR2 Statistic (1) R2 is a measure of how well the fit function follows the trend in the data. 0 ≤ R2 ≤ 1. Define: yˆ is the value of the fit function at the known data points.
