cattle: Cattle Data

Description Usage Format Details


Kenward (1987) reported an experiment in which cattle were assigned randomly to two treatment groups A and B, and their body weights were recorded in kilogram. Thirty animals received treatment A and another 30 received treatment B. The animals were weighted 11 times over a 133-day period; the first 10 measurements for each animal were made at two-week intervals and the last measurement was made one week later. Since no observation was missing, it is considered to be a balanced longitudinal dataset.
