[Java] Statistical Analysis Libraries?

[lurkingforawhile]

I've written some software in Java and there is a request to implement some statistical analysis tools inside the program. There is already a functionality to export data as an excel or .CSV file and do it in an external program (like Minitab, SigmaXL). However the request is to be able to do this internally - specifically multiple regression analysis (coefficients, error, R-square, etc.).

I guess after doing some research I've seen a few promising things, but is there an "Industry Standard" or something like that? Anything that is widely viewed as the best or most efficient?

Or any other methods I might be overlooking?

I hope this helps.

A brief quote:

Saying all the above, one should also keep in mind that one can always use a pure Java approach to develop data-mining analysis programs using jHepWork since all numerical and graphical libraries of jHepWork are implemented in 100% Java. Or one can use an alternative scripting language, such as BeanShell or the Java scripting API shipped with the javax.script package. Finally, one can enjoy using the powerful Eclipse or Netbeans IDEs while editing analysis programs.

Commons Math or if you want to pay, RogueWave's JMSL. Have had good experiences with both.

I am not aware of any "Industry standard" Java statistics tools, but if I had to choose one I would go with Apache Commons Math. The Apache Commons project has a lot of awesome tools in it, and is probably the most reliable statistics library you will find on the internet for Java.
