Consider a linear regression of K; E RIIX; E R1, 1' = 1, . . . ,n. Assume the following two eases and suppose that there is no way to x the violation of the assumption required in the linear regression for each ease. If you must choose one of the two cases, what is your choice? Verify your choice. Case 1: linearity between 1" and X does not holds, but oonstant variance is satised. Case 2: linearity between F and X holds, but constant variance fails
