+
+    The BILIRUBIN attribute appears to be continuously-valued.  I checked
+    this with the donater, Bojan Cestnik, who replied:
+
+      About the hepatitis database and BILIRUBIN problem I would like to say
+      the following: BILIRUBIN is continuous attribute (= the number of it's
+      "values" in the ASDOHEPA.DAT file is negative!!!); "values" are quoted
+      because when speaking about the continuous attribute there is no such 
+      thing as all possible values. However, they represent so called
+      "boundary" values; according to these "boundary" values the attribute
+      can be discretized. At the same time, because of the continious
+      attribute, one can perform some other test since the continuous
+      information is preserved. I hope that these lines have at least roughly 
+      answered your question.
