## Abstract The paper proposes a new method for the analysis of unreplicated factorial designs. The new method does not use an estimate of the error variance and has the potential to identify up to __m__ – 1 active contrasts, where __m__ is the number of contrasts in the study. It can be shown that
In this article, we present a test for dispersion e ects from the unreplicated 2 n-k regular fractional factorial designs. The proposed procedure for the identiÿcation of dispersion e ects uses the log-likelihood ratio based on normal errors. Some practical examples are given to illustrate the appli
