Variation in the character and use of Chicago area hospitals

Abstract

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.
