Behaviour of the posterior distribution in HMM models when the number of states is misspecified In this paper we study the asymptotic behaviour of the posterior distribution for parametric HMM models with finite number of components. We concentrate in particular on the case where the number of states of the hidden Markov chain in the…

The minimum spanning tree (MST) is simply the spanning subtree of smallest weight.  It is straightforward to construct the MST using one of several natural…
