摘要
En 中文
The comparison of 23 different methods of cluster analysis in a 4-stage sequential validation design is discussed. These stages included derivation, replication, external validation and cross-validation. Data were obtained from 750 alcohol abusers on a number of socio-behavioral variables. The solution given by Ward''s method of cluster analysis was particularly powerful in comparison to solutions yielded by other techniques.
