title: Etiological hypotheses in schizophrenia: cross-level analysis.
abstract: Used the multicausal hypothesis generation capabilities of multiple regression analysis of aggregate data to explore the complex etiology of schizophrenia. Attendant dangers of ecological inference are controlled by combining regression analysis with individual-level analysis of the same population. The resulting cross-level analysis adds a new dimension to our understanding.
