Question:
In Problem 3.12, you were asked to fit a model to the clathrate formation data in Table B.8.
Problem 3.12
A chemical engineer studied the effect of the amount of surfactant and time on clathrate formation. Clathrates are used as cool storage media. Table B. 8 summarizes the experimental results.
a. Construct a normality plot of the residuals from the full model. Does there seem to be any problem with the normality assumption?
b. Construct and interpret a plot of the residuals versus the predicted response.
c. In Problem 3.12, you were asked to fit a second model. Compute the PRESS statistic for both models. Based on this statistic, which model is most likely to provide better predictions of new data?
