Abstract
The transition functions for the correlated random walk with two absorbing boundaries are derived by means of a combinatorial construction which is ba sed on Krattenthaler's theorem for counting lattice paths with turns. Resul ts for walks with one boundary and for unrestricted walks are presented as special cases. Finally we give an asymptotic formula, which proves to be us eful for computational purposes.
