> 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 *UpdatingRegressionStream* Stream Decorator will be added to support this functionality. The function name will likely be called *updatingRegress*.
> The implementation will be provided by Apache Commons Math.
