The property of higher order is introduced into the classic Markov switching autoregression model in this paper. We use the technical of integrated higher order states to obtain small order expression for the newly model. Then we determine the order selection for autoregression part according to AIC criterion, and propose a likelihood function under the assumption of normal distribution to obtain estimation of higher order model parameters. Our model is practiced to analyze the stock return time series, and the numerical results show it can identify the range of periodic fluctuations of return series conveniently, and depict tiny characteristic of fluctuations effectively.
