83 Variations and Sum of Squares an intuition

In this econometrics tutorial, we dive into the core components of regression output: Total Sum of Squares (TSS), Explained Sum of Squares (ESS), and Residual Sum of Squares (RSS). Lydia breaks down the conceptual meaning of each, explaining how they represent different aspects of variation in your dependent variable. You'll understand how TSS measures the total variation in Y from its mean, ESS quantifies the variation explained by your regression model, and RSS captures the variation left unexplained. Grasping these intuitive ideas is crucial for understanding the underlying math and for future interpretations of R-squared and F-tests.
