TreeViewer is a Windows application designed to display and print trees developed on a UNIX workstation or server. The command files, data, and output files all initially reside on the UNIX platform, and the UNIX machine will do all the work of growing, pruning and selecting a tree. The Tree Navigator file, automatically generated by the UNIX version, is then opened directly on the PC. Using the point-and-click interface, you can interactively inspect detailed node reports and overall tree summary reports (including gains charts, variable importance tables, misclassifcation tables, and prediction success tables) for each size tree in the pruned sequence. You can also take advantage of the tree printing functionality otherwise accessible only in the regular GUI version of CART.
As an affordable add-on module to all CART for UNIX versions, TreeViewer brings your CART trees to life, TreeViewer:
- Facilitates interactive investigation of the tree,
- provides easy access to numerous reports,
- allows inspection of any of the sub-trees in the sequence of pruned trees in a single CART run, and,
- facilitates report quality printing of decision trees.
