Nettet28. apr. 2024 · If we want to do linear regression in NumPy without sklearn, we can use the np.polyfit function to obtain the slope and the intercept of our regression line. Then we can construct the line using the characteristic equation where y hat is the predicted y. \hat y = kx + d y^ = kx + d. k, d = np.polyfit(x, y, 1) NettetReturns the explained variance regression score. explainedVariance = 1 − v a r i a n c e ( y − y ^) v a r i a n c e ( y) Notes.
