Confidence Intervals for Random Forest Regression

Reported by: pfleck Owned by: gkronber
Priority: medium Milestone: HeuristicLab 3.3.15
Component: Algorithms.DataAnalysis Version: 3.3.13
Keywords: Cc:

Description

The IConfidenceBoundRegressionModel/Solution could also be implemented for Random Forest Regression by calculating the variance of the single trees.

A small ALGLIB change will be necessary since there is no method of returning the variance or the values for each single tree yet.

The implementation depends on #2597.
