Box-Jenkins MethodologyDate: 05/13/97 at 14:12:20 From: Carlitos Subject: Box-Jenkins Methodology Can you give information about Box-Jenkins methodology? Where and when was it developed? Who developed it? Do you have any examples of how it is used? I appreciate your help, Carlos Date: 05/13/97 at 22:03:44 From: Doctor Jodi Subject: Re: Box-Jenkins Methodology Hi! For questions like this one, you'll usually want to try a good searcher, like http://altavista.digital.com or (for math stuff), http://mathforum.org/library/ Here are some URLs I found: What is it? http://www.math.umbc.edu/~arghya/a6.html Where and by whom was it developed? http://www-tqg.upc.es/seccio_tqg/productes/foresee/foremeth.html (From the above site): The Box-Jenkins (Box and Jenkins, 1976) methodology for the analysis and forecasting of time series is widely regarded to be the most efficient forecasting technique, and is used extensively - specially for univariate time series. The three step strategy of identification, estimation and diagnostic checking, requires the person in charge of producing forecasts to have experience and knowledge. When the number of series to forecast is large (like in the case of a bank, an airline or a power utility) the task to model "by hand" becomes practically impossible. The fact that some simple techniques (like exponential smoothing) are still being used along with limited extensions of intervention analysis and transfer function, is basically the consequence of the operational difficulty of applying the methodology of Box and Jenkins. I hope this helps. You can find more information using the URLs above. -Doctor Jodi, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
