A random variable that is a time series is stationary if its statistical properties are all constant over time. A stationary series has no trend, its variations around its mean have a constant amplitude, and it wiggles in a consistent fashion , i. The latter condition means that its autocorrelations correlations with its own prior deviations from the mean remain constant over time, or equivalently, that its power spectrum remains constant over time.
A random variable of this form can be viewed as usual as a combination of signal and noise, and the signal if one is apparent could be a pattern of fast or slow mean reversion, or sinusoidal oscillation, or rapid alternation in sign, and it could also have a seasonal component. That is:. Lags of the stationarized series in the forecasting equation are called "autoregressive" terms, lags of the forecast errors are called "moving average" terms, and a time series which needs to be differenced to be made stationary is said to be an "integrated" version of a stationary series.
Random-walk and random-trend models, autoregressive models, and exponential smoothing models are all special cases of ARIMA models. The forecasting equation is constructed as follows. First, let y denote the d th difference of Y , which means:. Rather, it is the first-difference-of-the-first difference , which is the discrete analog of a second derivative, i. In terms of y , the general forecasting equation is:. Some authors and software including the R programming language define them so that they have plus signs instead.
