## Abstract Exact permutation testing of effects in unreplicated twoβlevel multifactorial designs is developed based on the notion of realigning observations and on paired permutations. This approach preserves the exchangeability of error components for testing up to __k__ effects. Advantages and l
Critical values of the test statistic proposed by Al-Shiha and Yang (1999) for analyzing unreplicated factorials are estimated by fitting an appropriate linear model. Some important properties of the test are also provided.
## 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__ β 1 active contrasts, where __m__ is the number of contrasts in the study. It can be shown that
