The guideline is that at some point, all the functionality in the org.apache.commons.math4.stat.descriptive package (and sub-packages thereof) of "Commons Math" should be provided by a new commons-statistics-descriptive maven module of "Commons Statistics". Perhaps that your proposed contribution fits that plan, but it is not obvious to me. For example, should there be a dedicated commons-statistics-descriptive-bigdecimal module? Or will the functionality be provided in a generic way? IMHO, a worthy principle, to be applied for the new components, is to avoid that they become a dump of numerous disparate little tools. Maybe I'm missing what you are getting at. Hopefully, someone else can comment (Eric?).
