Return the sphere of best fit for a set of 3D points.
- Parameters
- pointsarray_like

Examples
>>> import numpy as np
>>> from skspatial.objects import Sphere
>>> points = [[1, 0, 1], [0, 1, 1], [1, 2, 1], [1, 1, 2]] >>> sphere = Sphere.best_fit(points)
>>> sphere.point Point([1., 1., 1.])
>>> np.round(sphere.radius, 2) 1.0
