13 The logic of the algebra behind OLS

The tutor explores econometrics, focusing on Ordinary Least Squares (OLS) regression line fitting. They illustrate the vast number of potential lines for data points, explaining how OLS selects the best fit by minimizing the sum of squared residuals. The tutor emphasizes that OLS captures systematic variation in y and balances positive/negative residuals. Subscribe to @AxiomTutoring for more econometrics insights.
