In the statistical analysis of time series, the elements of the sequence are A sequence of random variables forms a stationary stochastic process only if the random variables are identically distributed. A stochastic process with the above definition of stationarity is sometimes said to be strictly stationary, but there are other forms of stationarity. Examples of non-stationary processes are random walk with or without a drift (a slow steady change) and deterministic trends (trends that are constant, positive, or negative, independent of time Equivalence in distributionreally is an equivalence relationon the class of stochastic processes with given state and time spaces.

To describe the time dynamics of the sample functions, Stationary Stochastic Processes A sequence is a function mapping from a set of integers, described as the index set, onto the real line or into a subset thereof. A time series is a sequence whose index corresponds to consecutive dates separated by a unit time interval. In the statistical analysis of time series, the elements of the sequence are 2020-04-26 stationary stochastic processes that until then had been available only in rather advanced mathematical textbooks, or through specialized statistical journals.

As in the case of stationary stochastic processes (cf. Stationary stochastic process), one distinguishes two types of such processes, namely stochastic processes with stationary increments in the strict sense, for which all finite-dimensional probability distributions of increments of $ X ( t) $ of a given order at the points $ t _ {1} \dots t _ {n} $ and $ t _ {1} + a \dots t _ {n} + a $ for Definition: A stochastic process is said to be stationary if the joint distribution of any subset of the sequence of random variables is invariant with respect to shifts in the time index, i.e., 2020-07-02 · Stationary stochastic processes (SPs) are a key component of many probabilistic models, such as those for off-the-grid spatio-temporal data. They enable the statistical symmetry of underlying physical phenomena to be leveraged, thereby aiding generalization. Prediction in such models can be viewed as a translation equivariant map from observed data sets to predictive SPs, emphasizing the Meaning of stationary stochastic process.
