Is there a Java library that implements one of the tests for the normality of a sample distribution?

Question

I have a dataset and I want to test to see how close it is to a normal or gaussian distribution. I know there are a variety of algorithms for doing this, eg. the Jarque-Bera test, the Anderson–Darling test and many others.

I'm hoping to find an open source Java implementation of one of these tests so that I don't need to implement it from scratch. Can anyone offer any pointers?

Answer 1

The statistical library SSJ:

1. Is licensed with GNU GPL
2. Is pure Java (no JNI)
3. Has Anderson–Darling

Answer 2

http://jdistlib.sourceforge.net/

this has many other normality test methods.
