Abstract

A method for detecting patterns using statistical analysis is provided. The method includes receiving a subset of structured data having a plurality of fields. A plurality of value combinations is generated for the plurality of fields using a statistical combination function. Each combination of the generated plurality of value combinations is stored as a separate entry in a results table. The entry in the results table includes a counter associated with the stored combination. A value of the counter is incremented for every occurrence of the stored combination in the generated plurality of value combinations. The results table is sorted based on the counters' values and based on a number of fields in each combination. One or more entries having highest counter values are identified in the results table.
