Bradley commented on SPARK-9622: -- OK, before you do though, it'd be worth discussing how those variances should be returned. E.g., just a Double column of variances? Pros: Simple, applicable to other distributions if we ever move beyond Variance (=Gaussian) as an impurity. Cons: Not extensible if we use other distributions and want to return more details about the distribution. Those are my thoughts. Currently, a Double column of variances seems best to me. But it'd be nice to hear your thoughts. > DecisionTreeRegressor: provide variance of prediction > - > > Key: SPARK-9622 > URL: https://issues.apache.org/jira/browse/SPARK-9622 > Project: Spark > Issue Type: Sub-task > Components: ML >Reporter: Joseph K.
