Abstract. In this paper, we present a simplified parsimonious higher-order multivariate Markov chain model with new convergence condition. (TPHOMMCM-NCC). Moreover, estimation method of the parameters in TPHOMMCM-NCC is give. Numerical experiments illustrate the effectiveness of TPHOMMCM-NCC. Different methods for multiple categorical data sequences prediction (which means the relationships of different categorical data sequences are taken into account) has been proposed, e.g., the first-order multivariate Markov chain model, higher-order multivariate Markov chain model and an improved multivariate Markov chain model (to speed up the convergence) [10]. (They add a negative association part which is multiplied a constant for normalizing solutions at the back of the positive association part of the model. ).
IntroductionThe organization of this article is organized as follows. In Section 2, we review some basic knowledge of Markov chain model. In Section 3, a simplified parsimonious higher-order multivariate Markov chain model with new convergence condition is proposed for multiple categorical data sequences. In Section 4, we estimate the parameters of the simplified parsimonious higher-order multivariate Markov chain model with new convergence condition. Numerical experiments show the effectiveness of our model in Section 5.
