The role of cluster analysis on traditional cephalometric dimensions.

In order to categorize (classify) craniofacial forms, varying linear dimensional arrays from a series of pretreatment cephalographs ('A' records) were subjected to cluster analysis. The derived subgroups (clusters) not only showed inconsistencies in their component patients, but also their 'nearest neighbors', i.e. cases identified as being most similar to one another. This study, therefore, emphasized the need to devise more appropriate cephalometric appraisal techniques for patient categorization (diagnosis).

Researching the symptoms of menopause: an exercise in methodology.

This paper deals with the methodological problems involved in the measurement of physical and psychological morbidity among menopausal women. A sample of 477 women were interviewed six times over a 3-yr period. In addition to questions about their menstrual status, the women were asked at each interview to complete a checklist of physical, menopausal, and psychological symptoms. Factor analysis was performed on the symptom experience to determine if symptoms could be grouped together in ways which would demonstrate clinically useful constructs and be stable over time. One-way analysis of variance showed a significant relationship only between the vasomotor symptoms and menopausal status.
