Statistics and Analytics Third-Party Libraries
MashZone NextGen Analytics includes the following third-party libraries with many common statistics and machine learning algorithms:
*Apache Commons Mathematics Library, version 2.2. Include web-apps-home/mashzone/WEB-INF/lib/commons-math-2.2.jar in the classpath.
*Apache Mahout Library, version 0.7. Include these jar files in the class path:
*web-apps-home/mashzone/WEB-INF/lib/hadoop-core-1.2.1.jar
*web-apps-home/mashzone/WEB-INF/lib/mahout-core-0.7.jar
*web-apps-home/mashzone/WEB-INF/lib/mahout-math-0.7.jar
User-defined analytics functions can leverage these libraries directly. Simply include the associated jar file in the classpath along with the jar for RAQL when you compile your UDF classes.
