Web14. jún 2024 · The process of fitting known geometric models to scattered data is well known and resolved since a long time. Indeed, Legendre was one of the first to use least … WebAs a first guess, I'd say the center of the sphere is simply the mean of your data points, if they're all weighted equally. With only one parameter left to fit, it should be easy enough. However, you may want to look at the paper: Werman, Michael and Keren, Daniel A Bayesian method for fitting parametric and nonparametric models to noisy data
