Joel Bernstein updated SOLR-11952:
----------------------------------
Description:
The current *olsRegress* function works on in-memory matrices. 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.
