Combining dummy variables with quantitative variables to see if slopes change across groups. Slide 11: Time-Series Econometrics (Stationarity) Spurious Regression: High R2cap R squared
Testing for stationary data using the Augmented Dickey-Fuller (ADF) test to avoid spurious regressions.

Slide 3: The Two-Variable Regression Model (The Core Foundation)
No perfect multicollinearity (for multiple regression). Slide 6: Hypothesis Testing and R-Squared ( R2cap R squared Goodness of Fit ( R2cap R squared ): Measuring the proportion of total variation in explained by the regression model. The -Test: Testing individual parameter significance ( The Combining dummy variables with quantitative variables to see
Unlike many technical PPTs, this one emphasizes the intuition behind concepts (e.g., "Why OLS is BLUE" using simple analogies before diving into matrix notation). Great for students who fear calculus.
Finding long-run equilibrium relationships between non-stationary time series. Slide 12: Panel Data Models Slide 6: Hypothesis Testing and R-Squared ( R2cap
