Abstract
In this paper exact constants are given for the rate of convergence of the solution x
n of the nonlinear difference equation towards the root θ of f under very general conditions on the steplengths an
, on the weighting factors bn
and on the random noise vn
. Moreover, an almost sure representation is developed for the deviation xn
– θ by weighted sums of (independent) random variables
