Now analyze the data in Exercise 14.18 using a mixed models approach within appropriate form for the covariance matrix. How do those results differ from the results you found in Exercise 14.18?

The following data come from Exercise 14.16 with some observations deleted. (An entry of “999” represents a missing observation.)

a. Analyse these data using a standard repeated measures analysis of variance.

b. How do your results differ from the results you found in Exercise 14.20?
