A computer-assisted method for determining a plurality of clusters is disclosed.
The disclosed method includes, for each of a plurality of observations, obtaining
a data set containing no more than one proxy value for each of a plurality of variables,
each variable having a plurality of possible values. The disclosed method also
includes, assigning each of the plurality of observations to one of a plurality
of clusters, and, for the plurality of observations and the plurality of variables,
via cluster reassignment, maximizing a processor-determined fitness score representing
a number of variables from the plurality of variables for which each observation's
proxy value corresponds to a mode for that observation's assigned cluster.
