+
+4. Relevant Information:n
+      Vina conducted a comparison test of her rule-based system, BEAGLE, the
+      nearest-neighbor algorithm, and discriminant analysis.  BEAGLE is 
+      a product available through VRS Consulting, Inc.; 4676 Admiralty Way,
+      Suite 206; Marina Del Ray, CA 90292 (213) 827-7890 and FAX: -3189.
+      In determining whether the glass was a type of "float" glass or not,
+      the following results were obtained (# incorrect answers):
+
+             Type of Sample                            Beagle   NN    DA
+             Windows that were float processed (87)     10      12    21
+             Windows that were not:            (76)     19      16    22
+
+      The study of classification of types of glass was motivated by 
+      criminological investigation.  At the scene of the crime, the glass left
+      can be used as evidence...if it is correctly identified!
