  2. 1. Analysis of Dispersion Effects in Unreplicated Factorial Designs

    Author : Kerstin Wiklander; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dispersion effects; location effects; two-level factorial experiment; fractional designs; Hadamard products; fractional designs;

    Abstract : Methods for estimating and testing hypotheses of dispersion effects in two-level unreplicated factorial designs are studied. Under a particular = normal model, some linear combinations of the response variables are constructed in order to make a simple inference. READ MORE
