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
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
On statistical analysis of Markov chains with conditional memory depth
A new mathematical model of the s-order Markov chain with conditional memory depth is proposed. Maximum likelihood estimators of parameters are constnicted and their properties are analyzed. A statistical test on parameter values is constructed. Numerical results are presented
