Deal all, It would be appreciated if someone could clarify the following on org.apache.commons.math.stat.univariate.Frequency.
My version of org.apache.commons.math is dated 10 August, 2004. The following snippet piece of code is from http://jakarta.apache.org/commons/math/userguide/stat.html#1.3%20Frequency%20distributions Frequency f = new Frequency(); f.addValue(1); f.addValue(new Integer(1)); // (*) f.addValue(new Long(1)); f.addValue(2); f.addValue(new Integer(-1)); System.out.println(f.getCount(1)); // displays 3 System.out.println(f.getCumPct(0)); // displays 0.2 System.out.println(f.getPct(new Integer(1))); // displays 0.6 System.out.println(f.getCumPct(-2)); // displays 0 System.out.println(f.getCumPct(10)); // displays 1 When I run it, I got the following exception at line (*). Exception in thread "main" java.lang.IllegalArgumentException: Value not comparable to existing values. It looks as though the default comparator can not compare primitive type int with Integer object. I thought this piece of code is supposed to demonstrate the otherwise. Thanks in advice for your help ! Shing ===== Home page : http://uk.geocities.com/matmsh/index.html ___________________________________________________________ALL-NEW Yahoo!
