Econometrics: Regression Analysis With Qualitative Information
I Dummy variable trap: Suppose you have a set of Then, if you include all these dummy variables and a constant term ( 0), you will have perfect multicollinearity. Also known as dummy variable trap. 5. Additive Dummy Variables I Additive dummy variables result in di erent intercepts for ... Doc Viewer
