Markov basis and Groebner basis of Segre-Veronese configuration for testing independence in group-wise selections
Satoshi Aoki, Takayuki Hibi, Hidefumi Ohsugi, Akimichi Takemura · 2007-04-09 · via math.ST updates on arXiv.org

We consider testing independence in group-wise selections with some restrictions on combinations of choices. We present models for frequency data of selections for which it is easy to perform conditional tests by Markov chain Monte Carlo (MCMC) methods. When the restrictions on the combinations can be described in terms of a Segre-Veronese configuration, an explicit form of a Gröbner basis consisting of moves of degree two is readily available for performing a Markov chain. We illustrate our setting with the National Center Test for university entrance examinations in Japan. We also apply our method to testing independence hypotheses involving genotypes at more than one locus or haplotypes of alleles on the same chromosome.
