Regression through the origin is a special case of linear regression in which the intercept term is omitted from the model, meaning the regression line is forced to pass through the origin (0,0). The model can be written as ( Y_i = \beta X_i + u_i ), where ( \beta ) is the slope coefficient and ( u_i ) is the error term. This specification is used when there is a strong theoretical justification that the dependent variable equals zero whenever the independent variable is zero. For example, in certain physical relationships or
