Multidimensional scaling methods were used to derive interpretable models of medical school similarity with respect to research and graduate medical education intensiveness. On the basis of cluster analysis, private schools seemed to be categorizable into those that are relatively intensive on both research and graduate medical education, those that are not intensive on either, and some that, along with some public schools, are both extensive (in absolute measure) and intensive (in relative measure) on graduate medical programs. These groups are readily apparent in the scaling model, but graduations of difference within groups are also apparent. The public schools showed similar separability along continuous dimensions of difference. The statistical analyses are discussed at length. (Author/MSE)
