Nettet29. des. 2024 · If a linear or polynomial fit is all you need, then NumPy is a good way to go. It can easily perform the corresponding least-squares fit: import numpy as np x_data = np.arange (1, len (y_data)+1, dtype=float) coefs = np.polyfit (x_data, y_data, deg=1) poly = np.poly1d (coefs) In NumPy, this is a 2-step process. NettetLinearRegression fits a linear model with coefficients w = (w1, …, wp) to minimize the residual sum of squares between the observed targets in the dataset, and the targets predicted by the linear approximation. Parameters: fit_interceptbool, default=True Whether to calculate the intercept for this model.
