In probability theory, stochastic drift is the change of the average value of a stochastic (random) process. A related term is the drift rate which is the rate at which the average changes. For example, the process which counts the number of heads in a series of coin tosses has a drift rate of 1/2 per toss. This is in contrast to the random fluctuations about this average value.
