Stationarity in time series analysis | by Shay Palachy ...

Apr 08, 2019· A common approach in the analysis of time series data is to consider the observed time series as part of a realization of a stochastic process. Two cursory definitions are required before defining stochastic processes. Probability Space: A probability space is a triple (Ω, F, P), where. (i) Ω is a nonempty set, called the sample space.
