depression | R Documentation |
The data correspond to an experiment in which a treatment for depression is studied. Two groups of patients (1: control / 2: treatment) have been followed at five different times (0: pre-test, 1: one month post-test, 3: 3 months follow-up and 6: 6 months follow-up). The dependent variable is a depression score.
Repeated measures ANOVA can be performed in order to determine the effect of the treatment and the effect of time on the depression score.
