A model selection test for an AR (1) versus an MA (1) model [PDF]

open access: yesStatistics & Probability Letters, 1992
This paper proposes a model selection test statistic for the choice between an AR(1) and an MA(1) model. It is a function of the first two sample autocorrelations of a time series. This establishes that it can be compared directly with a statistic given in Burke, Godfrey and Tremayne (1990).

Research on Hot Deformation Behavior of F92 Steel Based on Stress Correction

open access: yesMetals, 2022
In order to systematically study the stress correction method and hot deformation behavior of F92 stainless steel, the hot compression test was performed using a Gleeble-3500 (DSI USA, Connecticut, CT, USA) at strain rates of 0.01–10 s−1 and deformation ...

Interpolation based on stationary and adaptive AR(1) modeling [PDF]

open access: yes2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
In this paper, we describe a minimal mean square error (MMSE) optimal interpolation filter for discrete random signals. We explicitly derive the interpolation filter for a first-order autoregressive process (AR(1)), and show that the filter depends only on the two adjacent points.

Nationwide Radar-Based Precipitation Nowcasting—A Localization Filtering Approach and its Application for Germany

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
One approach to improve advection methods is the short-term ensemble prediction system (STEPS). STEPS decomposes precipitation fields into different spatial scales and filters those having a short lifetime.

A seasonal Integer-Valued AR(1) model with delaporte marginal distribution [PDF]

open access: yesمدل‌سازی پیشرفته ریاضی
Real-count data time series often show the phenomenon of over-dispersion. In this paper, we introduce the first-order integer-valued autoregressive process with seasonal structure.

Note on AR(1)-characterisation of stationary processes and model fitting

open access: yesModern Stochastics: Theory and Applications, 2019
It was recently proved that any strictly stationary stochastic process can be viewed as an autoregressive process of order one with coloured noise. Furthermore, it was proved that, using this characterisation, one can define closed form estimators for ...

The Linear Combination of ARIMA Models in Constructing the Areal Rainfall Using Thiessen Polygon Weighted Method [PDF]

open access: yesITM Web of Conferences
The construction of areal rainfall is crucial aspects in water resource management and disaster risk mitigation. The areal rainfall can be constructed as the linear combination of the actual rainfall in each stasion in the respected area.

Comparison of Estimation Procedures for Multilevel AR(1) Models [PDF]

open access: yesFrontiers in Psychology, 2016
To estimate a time series model for multiple individuals, a multilevel model may be used. In this paper we compare two estimation methods for the autocorrelation in Multilevel AR(1) models, namely Maximum Likelihood Estimation (MLE) and Bayesian Markov Chain Monte Carlo.
