Lecture 19. Endogenous Regressors And Instrumental Variables
Endogenous Regressors and Instrumental Variables The problem is that the dummy variable D is endogenous, i.e. there is a relation between D and u, e.g. because both are related to the same unobserved variable. If we This estimator is called the Two-Stage Least Squares (2SLS) estimator. ... Document Retrieval
