 as part of

 http://commons.apache.org/math/

 you have:

 http://commons.apache.org/math/apidocs/org/apache/commons/math/stat/descriptive/DescriptiveStatistics.html#addValue(double)

 however I don't see something like:

 addValue(new_val, NoV, Mean, Std_Dev, Skew)

 in order to get the new statistics based on the old one?

 It is very easy to do the Math to calculate the new Mean, Std_Dev and
Skew, based on the old values for a certain new value

 Why doesn't http://commons.apache.org/math/stat/ give you that?

 Thanks
 lbrtchx
