In this paper, we obtain characterizations of higherorder Markov processes in terms of copulascorresponding to their finite-dimensionaldistributions. The results are applied to establishnecessary and sufficient conditions for Markovprocesses of a given order to exhibitm-dependence,r-independence, or conditionalsymmetry. The paper also presents a study ofapplicability and limitations of different copulafamilies in constructing higher order Markovprocesses with the preceding dependence properties.We further introduce new classes of copulas thatallow one to combine Markovness withm-dependence orr-independence in timeseries.
