摘要: Some general remarks on random walks and martingales for finite probability distributions are presented. Orthogonal systems the multinomial distribution arise. In particular, a class of generalized Krawtchouk polynomials is determined by walk generated roots unity. Relations with hypergeometric functions some limit theorems discussed.
