title: A method to apply the robust estimator of dispersion, Qn, to fully-nested designs in the analysis of variance of microbiological count data.
abstract: This note outlines a method for the application of Rousseeuw's robust estimator of scale, Q(n), to fully-nested designs such as those used to estimate the components of variance in collaborative trials employed in quantitative food microbiology. A computer program is freely available on-line.
