In [probability theory](/source/probability_theory) and [statistics](/source/statistics), a '''zero-order process''' is a [stochastic process](/source/stochastic_process) in which each observation is independent of all previous observations. For example, a zero-order process in marketing would be one in which the brands purchased next do not depend on the brands purchased before, implying a fixed probability of purchase since it is zero order in regards to probability.
