WebApr 2, 2024 · 1. Method: Scipy.polyfit ( ) or numpy.polyfit ( ) This is a pretty general least squares polynomial fit function which accepts the data set and a polynomial function of any degree (specified by the user), and returns an array of coefficients that minimizes the squared error. A detailed description of the function is given here. WebOct 16, 2013 · This allows you to alter the degree of the polynomial fit quite easily as the function polyfit take thes following arguments np.polyfit(x data, y data, degree). Shown is a linear fit where the returned array looks like fit[0]*x^n + …
