Abstract

Abstract

There are several model formulations in current use for predicting tree-ring widths from climate variables. The results of such studies may aid in predicting past climate or in understanding how trees will respond to future climate change. However, it isn't clear if the results of such investigations depend on the particular modeling strategy selected. In an effort to answer this question, a general formulation is presented that includes the most commonly used models as special cases. The general formulation and selected special cases are then fit to the same tree ring dataset. Procedures are demonstrated for choosing among the various formulations based on information criteria and evaluating Kalman filter prediction errors.
