Abstract:  In this paper we explore how judgment can be used to improve statistical model selection for forecasting. We investigate the performance of various judgmental model selection methodologies against the benchmark statistical one, based on information criteria. We evaluate the performance of experts in terms of selecting the best model and forecasting performance, identifying major improvements. We examine how to extend statistical model selection to incorporate additional insights from experts.

Abstract:  High-dimensional pyramidal databases are common in the supply chains of large manufacturing companies. Such organizations often forecast shipments and consumption patterns at different hierarchical levels. Determining the most appropriate forecast aggregation approach is often a very computationally intensive task. Using a large food-processing firm data, we built a model that requires only correlation metrics and produces an accurate prediction of the optimal forecasting approach.

Abstract:  Customer preferences are not stable, especially where a consumer needs to make a complex or unfamiliar decision. In this research, the instability of consumer preferences for different attributes for a purposive sample of electronics products will be examined and compared from different angles with the aim of finding its influence on choice based conjoint analysis as a new product sales forecasting method.
