CART analysis help!

Postby Colin » Tue Apr 28, 2009 13:18


So I'm very new to this software, but am performing some data analysis and wanted to compare different methods/models for their predictive accuracies and am onto the CART model. I've been using orange for a very short time, but was able to follow the tutorials to build a tree for my data. Now, what I want to do is train that tree on partial data and use it to predict other pieces of the same dataset to see how well models predict stacked up against each other.

So my problem is that I don't really know how to get my tree to analyze other data once it is up and running and moreover how to get it to do the same analysis a couple hundred times (or so) in order to get accurate results that can then be compared.

I really really appreciate any help on this as I am totally new to this type of work!!
