Stochastic Processes.

A. Random Walk.

Let Xi, i = 1, 2, ...be independent random variables with:

P(Xi = +1) = p    

P(Xi = -1) = 1 - p

representing the direction a particle moves at each step, i.

The position, Sn, of the particle after n steps is

Sn = a + X1 + .... + Xn,

where a is the starting position.

The program generates a new set of random walks each time this page is loaded.

Random Walks for varying values of p.
