Hello I'm interested in Long Term Prediction over time series: regarding it, I and other guys have developed STRATEGICO, a free and opensource tool at http://code. google.com/p/strategico/ Please have a look at it, test it online with your own time series and give us any feedbacks and suggestions (new models?) .. Do you have any documentation or R libraries/tools to suggest? Regards Matteo http://www.redaelli.org/matteo/
