1. A computer based method for expanding attribute profiles to increase the strength of association between a query attribute and a set of attribute profiles associated with query-attribute-positive individuals, comprising:

  • a) receiving a query attribute;

    b) accessing a set of attribute profiles associated with a group of query-attribute-positive individuals;

    c) accessing a set of attribute profiles associated with a group of query-attribute-negative individuals;

    d) determining a first statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of attribute profiles associated with the group of query-attribute-positive individuals than in the set of attribute profiles associated with the group of query-attribute-negative individuals;

    e) expanding one or more attributes in the set of attribute profiles associated with the group of query-attribute-positive individuals and one or more attributes in the set of attribute profiles associated with the query-attribute-negative individuals to create a set of expanded attribute profiles associated with the group of query-attribute-positive individuals and a set of expanded attribute profiles associated with the group of query-attribute-negative individuals;

    f) determining a second statistical result indicating strength of association of the query attribute with an attribute combination having a higher frequency of occurrence in the set of expanded attribute profiles associated with the group of query-attribute-positive individuals than in the set of expanded attribute profiles associated with the group of query-attribute-negative individuals; and

    g) storing, when the second statistical result is higher than the first statistical result, the expanded attribute profiles associated with the group of query-attribute-positive individuals and the expanded attribute profiles associated with the group of query-attribute-negative individuals.
