WebJun 1, 2001 · The concept of ergodicity is fundamental in the analysis of economic time series and of dynamic models calibrated by time series data. It is, therefore, surprising that no general testing procedure has been proposed to examine this important hypothesis. The objective of this paper is to fill this gap for the case of Markov processes.

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. shell check if the current week day is friday

A random process with a mean that is time invariant and an autocorrelation function (Chapter 8) that is only dependent on time lag τ is called a wide sense stationary process.For ergodicity, one may also use more relaxed definitions (e.g., a random stationary process is ergodic in the mean if at least …
