R Programming for Statistics and Data Science - The Linear Regression Model

The video tutorial introduces linear regression as a method to approximate causal relationships between variables. It explains the simple linear regression model, highlighting the roles of dependent and independent variables, coefficients, and error terms. The tutorial discusses the importance of causal relationships in regression analysis, using income and education as examples. It also differentiates between population and sample data, emphasizing the use of estimated values in practice.
