The linear regression model is a fundamental tool in econometrics from "summary" of Introduction to Econometrics by Christopher Dougherty
The linear regression model plays a crucial role in econometrics as it allows economists to explore and understand the relationships between variables. By estimating the parameters of the model, researchers can analyze how changes in one variable affect another, providing valuable insights into economic phenomena. The simplicity of the linear regression model makes it an accessible tool for econometric analysis. Its straightforward structure, with a dependent variable that is a linear function of one or more independent variables, allows for easy interpretation of results. This simplicity is particularly valuable in econometrics, where complex relationships between variables can be challenging to untangle. Moreover, the linear regression model provides a clear framework for testing hypotheses in economics. By specifying a set of hypotheses about the relationships between variables, researchers can use the model to assess the empirical evidence and draw conclus...
