Multicollinearity: When independent variables are highly correlated (VIF test).

Heteroscedasticity: Non-constant variance of errors (Breusch-Pagan test).

Autocorrelation: Errors are correlated with each other (Durbin-Watson test).

method. Gujarati emphasizes that econometrics is not just about finding a line of best fit, but about understanding the "ceteris paribus" (all else being equal) relationship between variables. He meticulously breaks down how a dependent variable (like consumer spending) reacts to an independent variable (like disposable income), providing the mathematical proof for economic intuition. 2.

Multicollinearity – VIF, drop variables

The Gujarati PPT portable has several key features that make it a useful tool for students and instructors:

Slope ($\hat\beta_2$): $\frac\sum (X_i - \barX)(Y_i - \barY)\sum (X_i - \barX)^2$
Intercept ($\hat\beta_1$): $\barY - \hat\beta_2 \barX$
