The classical linear regression model is a widely used statistical technique for modeling the relationship between a dependent variable and one or more independent variables. It is based on a set of key assumptions that, when satisfied, allow for valid and reliable inference about the model parameters. These assumptions are crucial for making accurate predictions, performing hypothesis tests, and drawing meaningful conclusions from the regression analysis. The main assumptions of the classical regression model include:

1. Linearity: The relationship between the dependent variable and the independent variables is assumed to be linear. This means that changes in the independent variables are associated with constant changes in the expected value of the dependent variable, holding other factors constant.
