These data come from the study reported in Pierson and Ginther (1987), "Follicular population dynamics during the estrus cycle of the mare", Animal Reproduction Science, 14, 219-231.
Ovary.lis <- lmList(follicles ~ sin(2 * pi * Time) +
cos(2 * pi * Time),
data = Ovary, cluster = ~ Mare)
Ovary.lme <- lme(Ovary.lis)
