2.5.4.0 CONCLUSION
This unit discussed the use of dummy variable estimation to solve some variables that are existing or being introduced into a regression equation which are qualitative or immeasurable in numerical terms. In this discussion, students are made aware that the inherent assumption for the application of dummy variables is that the regression lines for the different groups differ only in the intercept term but have the same slope coefficients.
