156 Regression anatomy visualised

This video dives into regression anatomy, illustrating step-by-step how to effectively hold a variable constant in econometric analysis. We explore the challenge of a confounding variable, like ability (x2), contaminating both your independent (x1) and dependent (y) variables. Discover how to remove this influence by cleaning x1 and y through separate regressions, saving their residuals. Finally, learn how regressing these cleaned residuals reveals the true, uncontaminated effect of x1 on y, ensuring a pure measure of association. This visual explanation clarifies the concept of residualizing variables to isolate specific effects.
