Two-Threshold-Variable Integer-Valued Autoregressive Model

نویسندگان

چکیده

In the past, most threshold models considered a single variable. However, for some practical applications, with two variables may be needed. this paper, we propose two-threshold-variable integer-valued autoregressive model based on binomial thinning operator and discuss of its basic properties, including mean, variance, strict stationarity, ergodicity. We consider conditional least squares (CLS) estimation asymptotic normality CLS estimator under known unknown values. The performances are compared via simulation studies. addition, real data sets to underline superior performance proposed model.

Poisson Difference Integer Valued Autoregressive Model of Order one

This paper aims to model integer valued time series with possible negative values and either positive or negative correlations by introducing the Poisson difference integer valued autoregressive model of order one. This model has Poisson difference marginal distribution and is defined by a new operator called the extended binomial thinning operator. It includes previous integer valued autoregre...

Stationary solutions for integer-valued autoregressive processes

The purpose of this paper is to introduce and develop a family of Z+-valued autoregressive processes of order p (INAR(p)) by using the generalized multiplication F of van Harn and Steutel (1982). We obtain various distributional and regression properties for these models. A number of stationary INAR(p) processes with specific marginals are presented and are shown to generalize several existing ...

Threshold Variable Determination and Threshold Variable Driven Switching Autoregressive Models

In this paper we propose a new class of nonlinear time series models, the threshold variable driven switching autoregressive models. It is a hierarchical model that combines two important nonlinear time series models, the threshold autoregressive (AR) models and the random switching AR models. The underlying time series process switches between two (or more) different linear models. The switchi...
