I'm wary of dropping this in "Commons Statistics" without a broader view of the design of a package where it would perhaps fit with similar functionality for other number types. Could the class be generic? If so, what would be the API required to perform the operations? "Commons Numbers" has some suggestions[1][2]; those can, and should, be adapted to actual use-cases, such as "streams" (preferably before the first release). It would perhaps be helpful to know why there is no "BigDecimalStatistics" in the JDK.
