Hi senior members and Mark.

I'm a student computer science. I'm researching about ensemble in time series. I found that there are 2 learner in Weka, they had good accuracy. RandomForest and RandomCommittee.
I found a reference for RandomForest in Weka "
Leo Breiman (2001). Random Forests. Machine Learning. 45(1):5-32".
But RandomCommittee which i cannot see document for it.

My questions:
references can i find for RandomCommittee(Papers, authors) ?
I saw that multivariate forecasting is also applied in Weka in order to forecast multi series. where can i find references for multivariate forecasting which are implemented in weka ?

Thanks for your help.
