In physics, statistics, econometrics and signal processing, a stochastic process is said to be in an ergodic regime if an observable's ensemble average equals the time average. In this regime, any collection of random samples from a process must represent the average statistical properties of the entire regime. … See more The notion of ergodicity also applies to discrete-time random processes $${\displaystyle X[n]}$$ for integer $${\displaystyle n}$$. A discrete-time random process See more • An unbiased random walk is non-ergodic.
