  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

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik; Fysik; Physics;

    Abstract : In the optimisation process of radiographic imaging, factorial designed experiments can be applied. The parameters (factors) are varied together instead of one at a time, making it possible to discover interactions between the factors as well as main influences of them on the result variable.
