MCMC for Integer Valued ARMA Processes
نویسندگان
چکیده
The Classical statistical inference for integer valued time-series has primarily been restricted to the integer valued autoregressive (INAR) process. Markov chain Monte Carlo (MCMC) methods have been shown to be a useful tool in many branches of statistics and is particularly well suited to integer valued time-series where statistical inference is greatly assisted by data augmentation. Thus in the current work, we outline an efficient MCMC algorithm for a wide class of integer valued autoregressive moving-average (INARMA) processes. Furthermore, we consider noise corrupted integer valued processes and also models with change points. Finally, in order to assess the MCMC algorithms inferential and predictive capabilities we use a range of simulated and real data sets.

Binomial Arma Count Series from Renewal Processes
This paper describes a new method for generating stationary integervalued time series from renewal processes. We prove that if the lifetime distribution of renewal processes is nonlattice and the probability generating function is rational, then the generated time series satisfy causal and invertible ARMA type stochastic difference equations. The result provides an easy method for generating in...
متن کاملA Spectral Estimator of Arma Parameters from Thresholded Data
We consider computationally-fast methods for estimating parameters in ARMA processes from binary time series data, obtained by thresholding the latent ARMA process. All methods involve matching estimated and expected autocorrelations of the binary series. In particular, we focus on the spectral representation of the likelihood of an ARMA process and derive a restricted form of this likelihood, ...
متن کاملEstimation of latent Gaussian ARMA models for categorical behaviour data
We consider the tting of latent Gaussian models to categorical time series of cow feeding data. We derive a spectral quasi-likelihood for the data, and compare it with least squares ts to autocorrelations and MCMC estimators of the parameters in thresholded ARMA processes. We show that the spectral method is more e cient than least squares and far faster than MCMC.
متن کاملInteger Valued AR Processes with Explanatory Variables
Integer valued AR (INAR) processes are perfectly suited for modelling count data. We consider the inclusion of explanatory variables into the INAR model to extend the applicability of INAR models and give an alternative to Poisson regression models. An efficient MCMC algorithm is constructed to analyze the model and incorporates both explanatory variable and order selection. The methodology is ...
