Arts Plan: Implementation, Evolution, and Usage

This paper discusses the evolutionary development of an implemented, regression-based forecasting system used in planning and managing a schedule of performing arts events. In particular, the changing usage and refinement of this system is examined over a five-year period. One issue addressed is whether the manager, who can accept a regression forecast or revise it, is more accurate than the estimates produced by the regression model alone. The literature on bootstrapping and behavioral decision theory is used in examining the impact of managerial judgment on forecast accuracy. In addition, the paper presents a detailed review of the approaches used over time to revise the original forecasting system and an evaluation of their accuracy.
