Random walk patterns are also widely found elsewhere in nature, for example, in the phenomenon of Brownian motion that was first explained by Einstein. (Return to top of page.) It is difficult to tell whether the mean step size in a random walk is really zero, let alone estimate its precise value, merely by looking at the historical data sample.
