APPLYING MULTIVARIATE STATISTICAL ANALYSIS IN THE FORENSIC EXAMINATION OF HARD COPIES OF QUESTIONED DOCUMENTS
Abstract
Casework examples are used to demonstrate the application of multivariate statistical cluster analysis, and Ward's method in particular, to verify and clarify the results of questioned document examination obtained via traditional methods of biological analysis of document materials (paper substrate). The proposed method helps to control for subjective expert evaluation, and to characterize the differences and similarities between tested objects in a more detailed way.
