摘要: Abstract We consider testing hypotheses concerning comparing dispersions between two parameter vectors of multinomial distributions in both one-sample and two-sample cases. The comparison criterion is the concept Schur majorization. A new dispersion index proposed for hypotheses. corresponding test problem an exact test. For problem, bootstrap used to approximate null distribution statistic p-value. prove that asymptotically correct consistent. Simulation studies are reported a real life example presented.
