Hi there, Question 1: Anybody out there know if there is a way to retrieve a list/table of ctree terminal node stats? If I could get a list containing each terminal node, and distributional stats for the training observations allocated to it (e.g., mean, standard deviation, range), I would be a truly happy camper. I see ways to get predicted values for each observation in the training data, and I see how to get a list detailing which obs are in which terminal node, but I haven't yet figured out a way to get a list that just lists the terminal nodes and their stats.
Question 2: Is there a way to take a ctree and run an independent validation dataset through it? I'm probably being obtuse - it seems like this should be a really straight forward operation - but I'm just not getting it. I have a regression tree of elevations dependent on spectral data and geographic coordinates and would like to test it against my independent data. I can do this by shifting results back and forth through various image processing, GIS and Excel programs, but it seems like it would be more efficient to do it in R, if there is a way. Anybody know?
