Web1 Answer Sorted by: 7 As a clarification, the variable pcov from scipy.optimize.curve_fit is the estimated covariance of the parameter estimate, that is loosely speaking, given the data and a model, how much information is there in the data to determine the value of a parameter in the given model.

WebParameters ---------- order : int or sequence If an integer, it becomes the order of the polynomial to fit. If a sequence of numbers, then these are the explicit powers in the polynomial. A constant term (power 0) is always included, so don't include 0. Thus, polynomial (n) is equivalent to polynomial (range (1, n+1)). WebNov 28, 2024 · 1 Answer Sorted by: 6 I have two, non-exclusive hypotheses for the behavior. Floating point arithmetic is not sufficiently precise to represent large exponents and large factorials, causing catastrophic loss of precision. curve_fit isn't estimating the quantity that you want.
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, WebYou can use the least-square optimization function in scipy to fit any arbitrary function to another. In case of fitting a sin function, the 3 parameters to fit are the offset ('a'), amplitude ('b') and the phase ('c').
