PROC HPSPLIT Features. The default is the number of target levels. The goal of recursive partitioning, as described in the section Building a Decision Tree, is to subdivide the predictor space in such a way that the response values for the observations in the terminal nodes are as similar as possible. In other words, PROC HPSPLIT tries to split the data by each input variable and then chooses the best variable on which to split the data. The first step in the analysis is to run PROC HPSPLIT to identify the best subtree model: ods graphics on; proc hpsplit data=snra cvmethod=random(10) seed=123 intervalbins=500; class Type; grow. View solution in original post. The SAS kernel for Juypter is designed to enable users to write programs for SAS with Jupyter Notebooks. The HPSPLIT procedure provides two plots that you can use to tune and evaluate the pruning process: the cost-complexity analysis plot and the cost-complexity pruning plot. Using the FRACTION option can cause different numbers of observations to be selected for the validation set because this option specifies a per-observation probability.
