Main Effects Analysis in Clinical Research: Statistical Guidelines for Disaggregating Treatment Groups.
Lyons, John S.; Howard, Kenneth I.
Journal of Consulting and Clinical Psychology, v59 n5 p745-48 Oct 1991
Treatment outcome research generally relies on main effects analysis of variance to determine whether treatments are differentially effective. There is reason to consider disaggregating main effects even when conditions of heterogeneity of variance are not violated. Potential statistical significance of disaggregation can be shown to be function of reliability of dependent measure. (Author/NB)
