We study the dependence on initial conditions of two recursive filters for cleaning a contaminated time series from additive outliers. We show that the function in the recursive equation is in general not contractive, but nevertheless there exists a stationary solution and two iterates with arbitrary initial conditions coincide after some random time T0. However T0 may be quite large. 相似文献
