question 34

Essay

Your textbook only analyzed the case of an error-in-variables bias of the type $\widetilde { X _ { i } } = X _ { i } + w _ { i }$
What if the error were generated in the simple regression model by entering data that always contained the same typographical error, say $\widetilde { X } _ { i } = X _ { i } + a \text { or } \widetilde { X } _ { i } = b X _ { i }$ where a and b are constants. What effect would this have on your regression model?
