The Classical Linear Regression Model

Course Overview

This course provides an introduction to the Classical Linear Regression Model (CLRM) and the Ordinary Least Squares (OLS) estimator. Participants will learn to use the CLRM and OLS to discuss the assumptions needed for the OLS to deliver true regression parameters. The course will cover cases with one independent variable for one dependent variable, before progressing to regression analysis by generalising the bivariate model to multiple regression. Different model-building philosophies will be explored, with particular focus on the general-to-specific approach, and how to use goodness-of-fit statistics as the measures of “how well your model explains variations in the dependent variable”. Examples will be used to help clarify which kind of relationship is of interest, and how to interpret it. Participants will also have the opportunity to apply their learning to estimating the Capital Asset Pricing Model using real data with R.

This course is suitable for beginners, with little prior knowledge required, although an ability to graph two variables in the xy framework, an understanding of basic algebra and taking derivatives, and knowledge of matrix algebra will provide an advantage. By the end of the course, participants will be able to describe the problems that econometrics can help addressing, explain why some hypotheses are needed for the approach to produce an estimate, calculate the coefficients of interest in the classical linear regression model, interpret the estimated parameters and goodness of fit statistics, and estimate single and multiple linear regression models with R.

[Applications]
The application of this course can be seen in various fields such as economics, finance, and marketing. The Classical Linear Regression Model can be used to analyze the relationship between different variables and to make predictions. It can also be used to identify the factors that influence a certain outcome. Additionally, the course can be used to understand the assumptions needed for the OLS to deliver true regression parameters and to interpret the estimated parameters and goodness of fit statistics. Furthermore, the course can be used to estimate single and multiple linear regression models with R.
