Random walks have applications to engineering and many scientific fields including ecology, psychology, computer science, physics, chemistry, biology, economics, and sociology. The term random walk was first introduced by Karl Pearson in 1905. Visa mer In mathematics, a random walk is a random process that describes a path that consists of a succession of random steps on some mathematical space. An elementary example of a random walk is the random walk … Visa mer A popular random walk model is that of a random walk on a regular lattice, where at each step the location jumps to another site according to some probability distribution. In a simple random walk, the location can only jump to neighboring sites of the lattice, … Visa mer As mentioned the range of natural phenomena which have been subject to attempts at description by some flavour of random walks is … Visa mer • Branching random walk • Brownian motion • Law of the iterated logarithm Visa mer A random walk having a step size that varies according to a normal distribution is used as a model for real-world time series data such as financial markets.
