Not stationary; moving Definition from Wiktionary, the free dictionary A Non-Stationary Geometry-Based Cooperative Scattering Channel Model for MIMO Vehicle-to-Vehicle Communication Systems This study improves the statistical inference of the DD estimates, addressing seasonality, non-stationarity , and autocorrelation through the use of month fixed effects, a linear time trend, and mixed-effects modeling, respectively. If a non-stationary series, yt must be differenced d times before it becomes stationary, then it is said to be integrated of order d. We write yt ∼I(d). So if yt ∼I(d) then ∆dy t∼I(0).

These models for the trend imply that the series trend evolves in a perfectly predictable way, therefore they are called deterministic trend models. The 7th International Conference on Condition Monitoring of Machinery in Non-Stationary Operations (CMMNO 2021) will be held in Guangzhou during June 11-13, 2021.. The main objective of The International Conference on Condition Monitoring of Machinery in Non-Stationary Operations is to bring together the scientific community to discuss the major advances of condition monitoring of machinery in If these estimated residuals can be statistically shown to be stationary (more precisely, if one can reject the hypothesis that the true underlying errors are non-stationary), then the residuals are referred to as the detrended data, and the original series {Y t} is said to be trend-stationary even though it is not stationary. spanned by the common (possibly non-stationary) factors in the large approximate factor model X t= F t+ u t; (1) where F tis the r 1 vector of common factors and is an N rmatrix of factor loadings, with r<1. We will also make use of the scalar version of (1) X i;t= 0 iF t+ u i;t; (2) with 1 i Nand 1 t T. Definition of non-stationary in the Definitions.net dictionary.

A new Oxford Martin policy paper from Professor Sir David Hendry and Dr Felix Pretisexamines a fundamental problem in economic forecasting: that many models used in empirical research and for guiding policy have been based on treating observed data, such as Since stationarity is an assumption underlying many statistical procedures used in time series analysis, non-stationary data are often transformed to become stationary. The most common cause of violation of stationarity is a trend in the mean, which can be due either to the presence of a unit root or of a deterministic trend. If you're wondering why ARIMA can model non-stationary series, then it's the easiest to see on the simplest ARIMA(0,1,0): $y_t=y_{t-1}+c+\varepsilon_t$. Take a look at the expectations: $$E[y_t]=E[y_{t-1}]+c=e[y_0]+ct,$$ The expectation of the series is non-stationary, it has a time trend so you could call it trend-stationary though.

In the case of the ARIMA (1,0,0) (1,0,0)s model that you are fitting, both coefficients should be between -1 and 1 for the process to be stationary.

I give here a short introduction, with references below. If you are in a hurry, please read the first two pages of this recent article instead (arXiv:1802.08380).
