Hi Dex, 1 - You can view the Node Rules from View>Model>Node Rules in the Results window for the Decision Tree node to see the entire rule for each node in the tree.     2- For the Interactive Tree, make sure you are changing the Sample Size property under Interactive Sample, and you first need to set Create Sample to User.  There is another property above that called Node Sample that's different.  This is assuming you are on Enterprise MIner 13.1 or later - prior to that, you need to set the following macro variables in the Project Start Code:   EM_INTERACTIVE_TREE_MAXOBS — controls the maximum number of observations used for the interactive decision tree. The default value is dynamically controlled by the record length of your selected data set.  EM_INTERACTIVE_TREE_SAMPLEMETHOD — controls the sampling method used to create the data for the interactive decision tree. This is used in combination with EM_INTERACTIVE_TREE_MAXOBS. Valid values are FIRSTN, RANDOM, and STRATIFY. The default value is RANDOM.   Hope that helps, Wendy   ... View more
