Information Technology Transfer in Econometric Forecasting: A Pictorial Approach
以路易斯安那计量模型为例,提出用多层实体关系图来管理信息技术转移中的复杂因素,使预测过程更清晰、模型维护更方便,适合需要改进预测系统文档和任务管理的研究者。
Successful information technology transfer requires effective communication and clear, concise information exchange. This paper, using the Louisiana econometric model as a case study, proposes a pictorial approach to present and manage complex factors essential to information technology transfer. The approach utilizes multi-layer entity-relationship diagrams to provide a meaningful framework for the entire forecasting process, provide clarity to ensure better model maintenance when changes in social/economic structures require reformulations, and provide a procedural and data dictionary for clear documentation. The pictorial approach is both intuitive and readable, capable of serving as a task management tool, a model implementation aid, and a system maintenance resource.
