WebMar 16, 2024 · In general, the ergodicity of time series refers to the ergodicity of stationary processes, which means that the process averaged over time behaves identical to the process averaged over space. What is the significance of stationarity of a process in a model how ergodicity affects the system analysis? In probability theory, a stationary ergodic process is a stochastic process which exhibits both stationarity and ergodicity. In essence this implies that the random process will not change its statistical properties with time and that its statistical properties (such as the theoretical mean and variance of the process) can be deduced from a single, sufficiently long sample (realization) of the process.
