MORE ALGORITHMS
You’ll make smarter decisions with AnswerTree because you use the right algorithm for each situation. No other decision tree product has as many powerful and algorithms. Select from:

CHAID - a fast statistical multi-way tree algorithm to explore data efficiently Exhaustive CHAID - a thorough statistical multi-way tree algorithm to explore data exhaustively Classification and Regression Tree - an exhaustive binary tree algorithm to partition data and produce accurate homogeneous subsets QUEST - a statistical algorithm to select variables without bias and build an accurate binary tree model quickly and efficiently

BETTER LOOKING RESULTS
Now get presentation quality diagrams, tables and charts. Display bar charts, summary statistics tables or both in each node of the tree diagram to clearly present results.

INTERACTIVE INTERFACE
Display charts, tables and underlying data in separate windows whenever you focus on a node in the tree diagram. Prune branches or drag and drop nodes together to combine categories. Immediately see the impact on dynamically changing tables and charts.

ADVANCED FEATURES
Build your model on a subset of your data and validate it on the remainder for more reliable models. Reuse your model on new data and save the scores for further analysis. Plus, much more.
