Abstract:
A method of organizing the data records of a database into clusters, comprising the steps of:(a) representing one or more variables in each data record in a binary form, whereby the value of each bit is assigned based on the value of a variable; (b) choosing a set of variables from those represented in all of the data records, whereby principal component analysis of the set of variables yields distinct clusters of the data records; (c) applying principal component analysis to the chosen set of variables for a sample of the data records, whereby two or more principal component vectors are identified; (d) examining the scores of the chosen set of variables for the sample data records along the two or more vectors; (e) selecting those vectors of the two or more vectors for which the examined scores form distinct clusters; (f) formulating a test based on the selected vectors; and (g) performing the test formulated in step (f) on each data record, whereby the data records are organized into clusters.
