In this article our goal is to studying the stationary condition of EGARCH time series model
which is proved by Nelson (1991) but what we did is to prove it with more simple and clearly …

This paper concerned with studding a stability conditions of the proposed non-linear
autoregressive time series model Known as Pareto Autoregressive model, acronym is …

This article deals with proposed nonlinear autoregressive model based on Burr X
cumulative distribution function known as Burr X AR (p), we demonstrate stability conditions …

In this research we suggest a new non-linear time series model known Exponential Double
Autoregressive model of order P, EXPDAR (p), this model is depends on Double …

This paper deals with studding a stability conditions of the proposed non-linear
