Repeated measurements on leutinizing hormone in cows

Description

These data, reported by Raz(1989, Biometrics 54, 851-71) refer to an experiment which compared the concentrations of leutinizing hormone (LH) in 16 suckled and 16 non-suckled cows. Measurements were made daily from day 1 through to day 4 postpartum, and twice daily from day 5 through to day 10 postpartum. The cows were ovariectomised on day 5 postpartum.

The first column of the dataset defines the group (1 - non-suckled, 2 - suckled) while the remaining columns give the LH values at the successive recording times.

The data are used in the rp.rmplot example script.
