SUMMARY
This discussion centers on the fundamental concepts of econometrics, specifically focusing on estimators and the Ordinary Least Squares (OLS) method. Econometrics is defined as the application of statistical methods to economic data to give empirical content to economic relationships. An estimator is a rule or formula that provides estimates of population parameters based on sample data, while unbiasedness indicates that the expected value of the estimator equals the true parameter value. The OLS estimator minimizes the sum of squared differences between observed and predicted values, ensuring efficient parameter estimation.
