Summary This paper studies a method of adjusting the ordinary least squares residuals, when estimating and comparing dispersions, at various levels of factors in a replicated factorial experiment. Using a general dispersion model, theoretical results demonstrate the benefits of the method of adjusting residuals. An illustrative example is included.
