Calculate the stable random walk. There are 4 types of random walk you can specify: 11. Laplace(0,1). No skewess. 1. Experimental Laplace random walk via Gauss-Laplace transmutation. 22. Normal distribution N(0, sqrt(n))*epsilon. No skewess. 2. Binomial random walk, b*epsilon. This can produce skewness.
