Is there a way i can use `org.apache.commons.math4.stat.regression` library inside painless, or any third party lib support available in any form.

Hello,

No, it isn't possible to use any third party libraries in Painless, unless you do a change in the source code. Also, that would be a question for the Elasticsearch team.
