Stationarity in stochastic processes

Change-points, trends and transients

Non-stationary dynamics turn out to be important in practice.

Notes on detecting non-stationarity in stochastic processes/random fields.

Related: ensuring stability. If we have a system with stable dynamics and keep the distribution of the inputs the same, then it will end up stationary.
