Popis: Special Issue: SAMO 2010; International audience; In this paper, we present a general way to correct a positive bias which occurs in all the estimators in random balance design method (RBD) and in its hybrid version, RBD-FAST. Both these techniques derive from Fourier amplitude sensitivity test (FAST) and, as a consequence, are faced with most of its inherent issues. And up to now, one of these, the well-known problem of interferences, has always been ignored in RBD. After presenting in which way interferences lead to a positive bias in the estimator of first-order sensitivity indices in RBD, we explain how to overcome this issue. We then extend the bias correction method to the estimation of sensitivity indices of any order in RBD-FAST. We also give an economical strategy to estimate all the first-order and second-order sensitivity indices using RBD-FAST.
