Web18 de nov. de 2024 · It's said the expected distance in Brownian motion is 0, which I would call the average end-position, including (-) signs. But here I am interested in the average distance using only (+) signs! It's said the expected "spread" is √𝑝𝑞t (p,q .. probability for left,right, t.. time). Unfortunately I am not sure if "spread" is what I am ...
