Business Problem: The detection of release events in the annual growth increments of trees has become a central and widely applied method for reconstructing the disturbance history of forests. While numerous approaches have been developed for identifying release events, the preponderance of these methods relies on running means that compare the percent change in growth rates.

Case Study: This is a report on a rather unusual application of time series modeling, a project sponsored by the FEDERAL CUSTOM AGENCY in Berne, Switzerland. The main goal of this project is an improvement of so called unit value indices in external trade statistics.

Case Study: In this paper, we attempt to use the techniques of the historical-descriptive approach to doing science in the context of our own and other research on climate change and biological production in the Northeast Pacific Ocean. In particular, we explore attempts to detect and understand rapid shifts in the abundance and distribution of two major components - salmon and zooplankton - of the large marine ecosystem of the Gulf of Alaska.

Business Problem: Goodyear Engineering Products Division wanted a system that would enable them to automate the inclusion of inputs to accurately determine the “safety stock” for each product to minimize inventory while maintaining promised customer service levels.

Business Problem: Develop accurate forecasts and incorporate significant marketing variables (price, TV ads etc.) into a working model that would allow marketing and logistics to more effectively allocate resources.
