WizWhy analyzer and predictor is a data mining software tool.
WizWhy determines how the values of one field (selected as dependent variable) are affected by the values of other fields (independent variable). The dependent variable is analyzed as Boolean. The user may select a non-Boolean analysis.
WizWhy reveals all the if-then, if-then-not and if-and-only-if rules in the data under analysis. On the basis of the discovered rules, WizWhy:
summarizes the data
points out interesting phenomena
reveals necessary & sufficient conditions
points out unexpected cases (cases to be audited)
issues predictions for new cases
WizWhy applies the discovered rules (the model) to a new dataset (from the same population) and predicts the outcome for each record
