Statistical basis for exploring schizophrenia

Abstract
The authors illustrate the use of multivariate statistics as a tool for exploring diagnostic factors in schizophrenia in two areas: the derivation and replication of the 12-point flexible diagnostic system and the definition of schizophrenic subtypes. They suggest an interactive approach between clinician and statistician to ensure the optimal combination of clinical judgment and systematic data analysis. Statistical concepts are presented with a minimum of statistical terminology.
