Neuware -In seminars and graduate level courses I have had several opportunities to discuss modeling and analysis of time series with economists and economic graduate students during the past several years. These experiences made me aware of a gap between what economic graduate students are taught about vector-valued time series and what is available in recent system literature. Wishing to fill or narrow the gap that I suspect is more widely spread than my personal experiences indicate, I have written these notes to augment and reor ganize materials I have given in these courses and seminars. I have endeavored to present, in as much a self-contained way as practicable, a body of results and techniques in system theory that I judge to be relevant and useful to economists interested in using time series in their research. I have essentially acted as an intermediary and interpreter of system theoretic results and perspectives in time series by filtering out non-essential details, and presenting coherent accounts of what I deem to be important but not readily available, or accessible to economists. For this reason I have excluded from the notes many results on various estimation methods or their statistical properties because they are amply discussed in many standard texts on time series or on statistics.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 268 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -When I take up a new book I always read its conclusions first. For I have discovered that even difficult books have conclusions that are easy to read and that give a first idea of their content. Of course, I expect my readers to do this also! Indeed, the present book offers them an opportunity for generalizing the method. After having gone over chapter 14 they should preferably look through chapters 5, 2, 13 and 10, or at least some of these (in this or in other orders), before engaging into any thorough reading. The point is that-at appropriate places in other chapters-the reader will find proofs; and, as we all know, all the proofs that are worth something are unavoidably ponderous. Of course, it is good to have them but, again, the most suitable procedure not to lose interest in their development is, I think, to first provisionally grant their conclusions, in order to see where they lead us to. Then, to study the proofs once we have been convinced that the goal is worth some effort. This is the reason why I suggest that at least chapters 4 and 11 should, on a first reading, be skipped, at any rate, by the 'poets'! The problem, a new approach of which is described in chapter 4, did not come to light, at least in its present form, before 1964. The first experi mental investigations bearing on it date back from the seventies.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 196 pp. Englisch.
