Abstract. We study the LRT statistic for testing a single population i.i.d. model against a mixture of two populations with Markov regime. We prove that the LRT statistic converges to innity in probability as the number of observations tends to innity. This is a consequence of a convergence result of the LRT statistic for a subproblem where the parameters are restricted to a subset of the whole parameter set. Resume. Nous etudions la statistique du test de rapport de vraisemblance (TRV) pour tester un modele i.i.d. a une population contre un melange de deux populations a regime markovien. Nous prouvons que la statistique du TRV converge vers l’inni en probabilite quand la taille de l’echantillon tend vers l’inni. Ceci est une consequence d’...
