Claim One:
1. A method implemented on a general purpose computer with processor-executable program instructions configured to direct at least one processor and at least one stored data table including data useful for predictive analysis, for automatically selecting a preferred size tree or sub-tree among a plurality of trees, comprising: accessing a stored data table comprising a plurality of records and a plurality of columns; identifying a training set of records and a test set of records within the data table records; analyzing the training set to grow or prune a collection of at least one fitted tree or sub-tree, each tree or sub-tree having at least one node, at least one node of each tree or sub-tree being a terminal node; determining the training set records associated with each node of each tree or sub-tree; determining the test set records associated with each node of each tree or sub-tree; determining a direction agreement statistic and a rank match statistic associated with each node of each tree or sub-tree; analyzing the direction agreement statistic and the rank match statistic for each node of each tree or sub-tree; determining direction agreement and rank match agreement for each node of each tree or sub-tree; identifying zero or more of a preferred tree or sub-tree based on the step of determining direction agreement and rank match agreement; upon identifying at least one preferred tree or sub-tree, identifying zero or more of the at least one preferred tree or sub-tree having valid ranking, the valid ranking determined as a statistical function of only the test set records; and upon identifying at least one preferred tree or sub-tree having valid ranking, providing access to a decision maker to at least one preferred tree or sub-tree having valid ranking for generating predictive analytic output as a function of input data, wherein selection of at least one preferred tree or sub-tree having valid ranking is based on: direction agreement and rank match agreement, and a statistical function of only the test set records.
