This video provides a summary of what is meant by a time series being stationary, and explains the motivation for requiring that time series are stationary.

In t he most intuitive sense, stationarity means that the statistical properties of a process generating a time series do not change over time . It does not mean that  

We can make this definition more precise by first laying down a statistical framework for further discussion. In the case of the time series of disposable income it appears that the series is stationary after calculating the first differences of the natural logarithm. It flucuates around a relatively constant mean, exhibits a rather constant variance and is more erratic as the detrended series. 2 The p-value is now below the significance level — so the time series can be declared as stationary.

Time series which exhibit a trend or seasonality are clearly not stationary. We can make this definition more precise by first laying down a statistical framework for further discussion. In the case of the time series of disposable income it appears that the series is stationary after calculating the first differences of the natural logarithm. It flucuates around a relatively constant mean, exhibits a rather constant variance and is more erratic as the detrended series.

Doing so then leads to the notion of weak stationarity. Definition 1.2.2 (Weak Stationarity). A stochastic process \((X_t\colon t\in T)\) is called weakly stationary if This video provides a summary of what is meant by a time series being stationary, and explains the motivation for requiring that time series are stationary. Associated with each stationary stochastic process is a spectral density function which is used to characterize frequency properties of a stationary time series.
