Frequent visitors to ForPrin.com may have noticed that the Forecasting Methodology Tree and the Forecasting Method Selection Tree have changed. Earlier this year, we replaced the Trees with versions that better represent the current state of forecasting knowledge. Since then, we have been fixing and revising the pop-up windows so that they are consistent with the new Trees. The Trees remain a work in progress--we will continue to improve the pop-up descriptions and add relevant links--so please let us know if you spot any problems or have any suggestions for improvements. See the links to the new Trees in the menu bar at the top of the screen.
The Forecasting Principles site summarizes all useful knowledge about forecasting so that it can be used by researchers, practitioners, and educators. The site is devoted to improving decision making by furthering scientific forecasting.
