Unformatted text preview: change? 2. The attached data set was generated from a repeated measures experiment. The factors have been given conventional repeated measures model names: Group, Subject (nested in Group), and Time. Do the measurements (the variable Response) over Time seem correlated? In PROC MIXED, ﬁnd a model that provides the best ﬁt (using AIC) of the covariance structure for the repeated measures factor Time . 3. Consider the following crossover design: Female Male Period 1 2 3 1 2 3 1 A=21 B=16 C=14 B=12 C=14 A=16 2 B=15 C=13 A=22 C=9 A=17 B=10 3 C=13 A=16 B=15 A=14 B=15 C=12 (a) Ignoring Gender, construct a model for this data set and analyze it. (b) Include Gender as a factor and reanalyze the model. Does the inference change if you include a Gender*Treatment interaction? Compare results from the separate analyses. 1...
