(a) Prepare partial regression plot for each of the predictor variables
(b) Do your plots in part (a) suggest that the regression relationships in the fitted regression function in homework 3 are inappropriate for any of the predictor variables? Explain.
When identifying the marginal relation for a predictor variable graphically, we use Partial regression plot. If there are some linearity, we usually conclude that variable is significant. The graphical identifying methods are somewhat subjective, I cannot tell whether there are linearity or not with certainty. But I think that in every plots we can see linearity. So, I think, we fitted the model in HW3 quite well.
