Thank you, Rahul, for helping out with the ticket. I was able to implement the
baseline ref with the above approach. :)
We could close the ticket. Let me know if anything needs to be done to mark it
solved.

> Key: MADLIB-1299
> URL: https://issues.apache.org/jira/browse/MADLIB-1299
> Project: Apache MADlib
> Issue Type: Improvement
> Components: Module: Linear Regression, Module: Logistic Regression,
> Module: Multinomial Logistic Regression
> Reporter: Pratik
> Assignee: Rahul Iyer
> Priority: Minor
>
> When we perform regression between dep vs independent variables currently
> function does not support control over baseline reference for the independent
> variable.
> I am not sure if Madlib does it internally with 1.15.1 release. If that is
> the case it would be awesome to have documentation and get the return value
> of the baseline variable.
