Random walk information

mathematics, a random walk, sometimes known as a drunkard's walk, is a random process that describes a path that consists of a succession of random steps on...

The random walk hypothesis is a financial theory stating that stock market prices evolve according to a random walk (so price changes are random) and thus...

signal noise produced by Brownian motion, hence its alternative name of random walk noise. The term "Brown noise" does not come from the color, but after...

probability theory, a branching random walk is a stochastic process that generalizes both the concept of a random walk and of a branching process. At every...
