Statistical analysis of high-order Markov dependencies
The paper deals with parsimonious models of integer valued time series. Such models are special cases of high-order Markov chain with a small number of parameters. Two new parsimonious models are presented. The first is Markov chain of order s with r partial connections, and the second model is called Markov chain of conditional order. Theoretical results on probabilistic properties and statistical inferences for these models are given
ВЕКТОРНАЯ ЦЕПЬ МАРКОВА С ЧАСТИЧНЫМИ СВЯЗЯМИ И СТАТИСТИЧЕСКИЕ ВЫВОДЫ О ЕЕ ПАРАМЕТРАХ
A new mathematical model of discrete time series is proposed. It is called homogenous vector Markov chain of the order s with partial connections. The conditional probability distribution for this model is determined only by a few components of previous vector states. Probabilistic properties of the model are given: ergodicity conditions and conditions under which the stationary probability distribution is uniform. Consistent statistical estimators for model parameters are constructed.Предложена новая малопараметрическая модель дискретных временных рядов – однородная векторная цепь Маркова s-го порядка с частичными связями, для которой условное распределение вероятностей определяется лишь некоторыми компонентами предыдущих векторов-состояний. Установлены вероятностные свойства модели: критерий эргодичности, условия, при которых стационарное распределение вероятностей является равномерным. Построены состоятельные статистические оценки параметров модели
On statistical estimation for markov chain of conditional order
The paper deals with Markov chain of conditional order, which is a special
case of a high-order Markov chain with a small number of parameters. Estimator

comparison of different Markov models via Bayesian information criterion are
presented
Identification of Markov Chains of Conditional Order
A new special case of high-order Markov
chains with a small number of parameters – Markov
chain of conditional order – is considered. Statistical
estimators for parameters of the model by observed time
series are constructed; their asymptotic properties are
analyzed. Results of computer experiments are presented
