This document introduces the Simple Linear Regression Model and explains the fundamental concept of the Least Squares Principle, which is used to estimate the best-fitting line by minimizing the sum of squared errors. It includes a step-by-step derivation of OLS estimators, helping students understand how the slope and intercept are obtained mathematically.
The material also covers the numerical properties of OLS estimators, such as their dependence on sample data, along with key statistical properties like unbiasedness and efficiency under standard assumptions. To enhance understanding, a numerical example is provided, demonstrating the practical application of these concepts.
This resource is ideal for beginners in econometrics who want a clear and concise understanding of simple linear regression and the working of OLS estimation.
