WebNote that the fit here is particularly poor due to the middle $(x_0,y_0)$ point being offset to the left from the bulk of the data, since I currently always include that center point in the arc. This still works better than fitting with the moments, though, as it imposes that the points cover a roughly 20 degree portion of the circle. Web$\begingroup$ Knowing the underlying problem as ubpdqn points out is critical. If all one needs is a circle that looks good visually, then the above method works fine (and that's not to take away from the above method). But if statistical inferences need to be made about the parameters, then a model that mimics the data generation process is ...
