May 11, 2014 · scipy.stats.linregress(x, y=None) [source] ¶. Calculate a regression line. This computes a least-squares regression for two sets of measurements. Parameters: x, y : array_like. two sets of measurements. Both arrays should have the same length.

LinearRegression 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.

Linear Regression: SciPy Implementation. Linear regression is the process of finding the linear function that is as close as possible to the actual relationship between features. In other words, you determine the linear function that best describes the association between the features. This linear function is also called the regression line. You can implement linear regression with SciPy.
