Web Reference: Implements ordinary least squares (OLS) to estimate the parameters of a multiple linear regression model. XT X b = XT y . To solve the normal equations, this implementation uses QR decomposition of the X matrix. (See QRDecomposition for details on the decomposition algorithm.) Jul 23, 2025 · In this code, we will demonstrate how to perform Ordinary Least Squares (OLS) regression using synthetic data. Fitting the OLS Model: Using statsmodels OLS function, we fit a linear regression model to our data. Let’s create our first predictive model using linear regression, with runDifference as the sole explanatory variable. Here we use Smile’s OLS (Ordinary Least Squares) regression model.
