Errors are not correlated across observations. 4. OLS Estimation and Goodness of Fit OLS works by minimizing the Sum of Squared Residuals ( Key Statistics: Coefficient of Determination ( R2cap R squared ): Measures the proportion of the total variation in explained by the regression model ( ). It ranges from 0 to 1. Adjusted R2cap R squared R̄2cap R bar squared ): Penalizes the R2cap R squared for adding unnecessary variables, preventing overfitting. 5. Hypothesis Testing and Interval Estimation Once we have estimated coefficients ( ), we need to know if they are statistically significant. basic econometrics gujarati ppt

Using t-tests for individual significance and F-tests for overall model fit. Coefficient of Determination ( R2cap R squared vs. Adjusted R̄2cap R bar squared ): Penalizing the addition of irrelevant variables. Diagnostic Checking: Relaxing OLS Assumptions Multicollinearity
