I'm trying to find a good open source software to do sales forecasting using Holt Winters and Box Jenkins time series algorithm. Somebody pointed me that R is the best open source available for statistical computing. Are there functions to do Holt Winters and Box Jenkins time series prediction in R? If there is none, can some one point me a good GNU/freeware to do the sales forecasting using the above algorithms? Appreciate your help. Thanks, Gopal [[alternative HTML version deleted]]

Using ts objects is not entirely trivial, though. Dirk -- Those are my principles, and if you don't like them... well, I have others. -- Groucho Marx
R can apparently handle it, according to "www.r-project.org" -> search -> "R site search". hope this helps. spencer graves Gopal Annasundaram wrote:>I'm trying to find a good open source software to do sales forecasting using Holt Winters and Box Jenkins time series algorithm.
