10.5.2.1 Properties of Autocorrelation Functions for WSS Processes As defined earlier, the autocorrelation function of a wide-sense stationary random process X (t) is defined as R XX t, t + τ = R XX τ The properties of autocorrelation functions of wide-sense stationary processes include the following: Since a stationary process has the same probability distribution for all time t, we can always shift the values of the y’s by a constant to make the process a zero-mean process. So let’s just assume hY(t)i = 0. The autocorrelation function is thus: κ(t1,t1 +τ) = hY(t1)Y(t1 +τ)i Since the process is stationary, this doesn’t depend on t1, so we’ll denote Stationary Process WEAK AND STRICT STATIONARITY NONSTATIONARITY TRANSFORMING NONSTATIONARITY TO STATIONARITY BIBLIOGRAPHY Source for information on Stationary Process: International Encyclopedia of the Social Sciences dictionary.

Actually, in Stationary Processes a related result has already been proved, which shall be recalled here: Let ξ()n be a centered weakly stationary sequence, and (.)Z is the associated spectral To tell if a process is covariance stationary, we compute the unconditional ﬁrst two moments, therefore, processes with conditional heteroskedasticity may still be stationary.

### A random process is called stationary if its statistical properties do not change over time. For example, ideally, a lottery machine is stationary in that the properties of its random number generator are not a function of when the machine is activated.

P[ Sn1. 5 Oct 2015 Here we explore some properties of both natural and horizontal visibility graphs associated to several non-stationary processes, and we pay 6 Oct 2009 stochastic stationary long memory process is quite important for the economic and 2 Some Probabilistic Properties of Stationary Processes. 8. in the time domain, and we make use of the property that geophysical data represent realizations that are strongly white non-stationary stochastic processes. Week 5.3: Spectral density of a wide-sense stationary process-17:49 So we either speak on strict stationarity and discuss the properties of complete processes, in particular, the autocovariance function which captures the dynamic properties of a stochastic stationary process. This function depends on the units Stationary Processes. Stochastic processes are weakly stationary or covariance stationary (or simply, stationary) if their Stationary & Weakly Dependent Time.
