+3. Past Usage:
+     1. CART book (above):
+        -- Optimal Bayes classification rate: 86% accuracy
+        -- CART decision tree algorithm: 72%
+        -- Nearest Neighbor Algorithm: 78%
+           -- 300 training and 5000 test instances
+
+4. Relevant Information:
+     -- 3 classes of waves
+     -- 21 attributes, all of which include noise
+     -- See the book for details (49-55, 169)
+     -- waveform.data.Z contains 5000 instances
+
+5. Number of Instances: chosen by user
+
+6. Number of Attributes:
+    -- 21 attributes with continuous values between 0 and 6
+
+7. Attribute Information:
+    -- Each class is generated from a combination of 2 of 3 "base" waves
+    -- Each instance is generated f added noise (mean 0, variance 1) in 
+       each attribute
+     -- See the book for details (49-55, 169)
+    
+8. Missing Attribute Values: none
+
+9. Class Distribution: 33% for each of 3 classes
