Is there a Java library for better linear regression? (E.g., iteratively reweighted least squares) [closed]

Answer 1

I don't fully understand your question, but I've used Apache Commons Math to do linear regressions before.

Answer 2

If you want to use a more generic external tool for this, use Octave. I think it's more suitable for these kind of things. If not, take a look to:

Logistic Regression in Java Specifically: http://commons.apache.org/math/userguide/overview.html
