This report summarizes briefly three of the analyses of variations made by the Chicago Regional Hospital Study in order to reduce a large number of demographic and ecologic variables to a small number of controlling variables. The correlations determined are intended to be used in the construction of a descriptive simulation model, from which can be generated a predictive model and, eventually, a prescriptive model capable of testing alternative future plans for the hospitals of the region.
本报告简要总结了芝加哥地区医院研究进行的三项变异分析，以便将大量人口统计学和生态学变量简化为少数控制变量。所确定的相关性旨在用于构建描述性模拟模型，由此可以生成预测模型，并最终生成能够测试该地区医院未来替代计划的规范性模型。
