Repeated Measures Analysis of Means in Clinical Research

James Jaccard, Lee Ackerman

Research output: Contribution to journalArticlepeer-review


Assumptions for analyzing treatment means in repeated measures designs are noted. The traditional F test has been shown to have limitations, given violations of the assumption of sphericity. This assumption is probably infrequently satisfied in clinical applications. Analytic alternatives based on a three-step Geisser-Greenhouse approach are discussed.
