Before revision:  In a first numerical study we demonstrate a backward dual regression algorithm in a Wiener environment that is easy to implement and is regarding accuracy comparable with the method of Belomestny et. al. (2009)  .
After revision:  In a first numerical study we demonstrate a backward dual regression algorithm in a Wiener environment that is easy to implement and is regarding accuracy comparable with the method of Belomestny et. al. (2009) regarding accuracy, but regarding computational robustness there are even several advantages .
