Whether one should use an analysis of covariance or a form of difference score test
(difference as an outcome or repeated measure) is not always clear. The literature on the …

The goal of this study was to investigate the performance of Hall's transformation of the
Brunner-Dette-Munk (BDM) and Welch-James (WJ) test statistics and Box-Cox's data …

In this power study, ANOVAs of unbalanced and balanced 2 x 2 datasets are compared (N=
120). Datasets are created under the assumption that H1 of the effects is true. The effects are …

Several methods have been proposed for the analysis of data from single-subject research
settings. This research focuses on the modifications of ANOVA-based tests proposed by …

The usual t-test or F-test can not be used to analyze unreplicated two-level factorial designs,
since all the observations are used to estimate the factor effects and no observation is left to …

In the one-way ANOVA, we consider procedures that determine whether μi= μj or μi< μj
when the means are known a priori to be nondecreasing. It is known that the one-sided …

Nonequivalent controlled pretest-posttest designs are central to evaluation science, yet no
practical and unified approach for estimating power in the two most widely used analytic …

Repeated measures ANOVA and mixed-model designs are the main classes of
experimental designs used in psychology. The usual analysis relies on some parametric …

A complete guide to cutting-edge techniques and best practices for applying covariance
analysis methods The Second Edition of Analysis of Covariance and Alternatives sheds new …

One approach to the analysis of repeated measures designs allows researchers to model
the variance-covariance structure of their data rather than presume a certain structure as is …
