The repeated measures data are available in the data frame residue in the R package daewr.

answer the following questions

(a) Fit a multivariate model using the lm function and then use the Anova function in the

car package to compute the sphericity test and determine if the Huynh-Feldt condition

holds.

(b) From the output of the Anova function used in (a) examine the Greenhouse-Geisser

and Huynh-Feldt adjusted F-tests of the sub-plot effects (are they significant?).

(c) Do you find more terms significant using the adjusted F-tests than were found using

the growth curve analysis
