Component/s: streaming expressions
> Add onlineRegress Stream Decorator to support Streaming Regression
> ------------------------------------------------------------------
>
> Key: SOLR-11952
> URL: https://issues.apache.org/jira/browse/SOLR-11952
> Project: Solr
> Issue Type: New Feature
> Components: streaming expressions
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
> Fix For: 8.1, main (9.0)
>
>
> The current *olsRegress* function works on an in-memory matrix. It would be nice to also have an online updating multivariate regression implementation that works with data sets of any size.
> This ticket will add support for *Miller Updating Regression*, which can be used with data sets of any size. An *OnlineRegressionStream* Stream Decorator will be added to support this functionality. The function name will likely be called *onlineRegress*.
> The implementation will be provided by Apache Commons Math.
