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

    Författare :Kerstin Wiklander; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :dispersion effects; location effects; two-level factorial experiment; fractional designs; Hadamard products; fractional designs;

    Sammanfattning : 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. LÄS MER
