Dear all, I am wondering how/if it is possible to implement the general methodology of Box and Tiao: "Intervention analysis with applications to economic and environmental problems" (JASA, 1975, pages 70-79) in R? This question has been posted before but without a positive response (at the time): tolstoy.newcastle.edu.au/R/help/06/03/22934.html Perhaps there have been some new developments in the meantime, though I was not able to find any on my own. Please (also) respond directly to me: mwolf at iew.uzh.ch. Thanks much, Michael
