Finding long-term equilibrium relationships between non-stationary time series. 3. What to Look for in an Updated (UPD) PPT Deck
Occurs when explanatory variables are highly correlated, making it hard to isolate individual effects. Heteroscedasticity: When the variance of the error term ( ) is not constant. basic econometrics gujarati ppt upd
Updated PPTs emphasize the Gauss-Markov assumptions. These must hold for estimators to be reliable. The regression model is linear in parameters. Assumption 2: values are fixed in repeated sampling. Assumption 3: Zero mean value of disturbance Assumption 4: Homoscedasticity (equal variance of Assumption 5: No autocorrelation between disturbances. Heteroscedasticity: When the variance of the error term
