1. A computer-implemented method of partitioning data records in a computer into groups, comprising the steps of:

  • (a) defining a function of a distribution of values of a designated variable associated with the data records, wherein the function comprises a combination of measures of entropy and adjacency, adjacency being weighted by a weighting factor;

    (b) partitioning the values of the designated variable into two or more groups, wherein a value of the function is determined by applying an optimization procedure; and

    (c) assigning a data record to a group according to the values of the designated variable.
