Multiple linear Regression If we observe a pattern of non constant variance in the residuals versus ; plot , we can try O a. Try a transformation on Y like VY or log(Y) for example. O b. Ignore as long as the plots of residuals vs the other Ik (k / j) look good. O c. Changing the scale of the residual plot. O d. See which points we can throw away to make the plot look good
