Let b0 and b1 be the slope and intercept from a linear model fitted to a particular data.After estimation you come to realize that X was misspecified and the true value of X is X' = 2*X +3
a) Can you get the correct estimate without refitting the model? find them in terms of b0 and b1(For extremly large datasets,this re-computation can be very expensive)
b) Suppose Y is misspecified this time and the Y' = 3*Y-5.Can you still retrieve the estimates?
c) Suppose your new response is log(Y).comment on whether you can repeat the above steps
