Github user jkbradley commented on the pull request:
    @MechCoder Thanks for the updates!  We'll need to use traits to fix the multiple inheritance
    sealed trait LogisticRegressionSummary
    sealed trait LogisticRegressionTrainingSummary
    class BinaryLogisticRegressionSummary extends LogisticRegressionSummary
    class BinaryLogisticRegressionTrainingSummary extends BinaryLogisticRegressionSummary
with LogisticRegressionTrainingSummary
    * LogisticRegressionSummary could be an abstract class if it saves a lot of code, but
if not, I'd prefer it remain a trait.
    * I'm marking the traits sealed so that we can extend them in the future without breaking
the public API.
    * These classes and traits will need to be public.
    Let me know if you have alternate ideas for these items.
