Hello,

I am running classification trees fro the purpose of predicting dividends.
I have training and test data sets, but am running to issues when
evaluating the prediction accuracy of the tree as it isn't a simple
'predict' formulation as the determinant variable is not a simple set of
classifying inputs. I think there is some RMSE method to use but can't
uncover how to do this. Any help would be greatly appreciated.
