WebDec 29, 2024 · Of course, with np.polyfit we are not restricted to fitting lines, but we can fit a polynomial of any order if enough data points are available. The question is just if it makes sense. For instance, if we fit a polynomial of degree 10 to the data, we get the following result. coefs = np.polyfit(x_data, y_data, 10) poly = np.poly1d(coefs) WebTo obtain the covariance matrix of the parameters x, cov_x must be multiplied by the variance of the residuals – see curve_fit. infodict dict. a dictionary of optional outputs with the keys: nfev.
