OBrienKaiser: O'Brien and Kaiser's Repeated-Measures Data

Description

These contrived repeate-measures data are taken from Table 7 of O'Brien and Kaiser (1985). The data are from an imaginary study in which 16 female and male subjects, who are divided into three treatments, are measured at a pretest, postest, and a follow-up session; during each session, they are measured at five occasions at intervals of one hour. The design, therefore, has two between-subject and two within-subject factors. The contrasts for the treatment factor are set to $-2, 1, 1$ and $0, -1, 1$. The contrasts for the gender factor are set to contr.sum.
