Abstract
An information-theoretic method clusters and merges bi-variate normal data or ‘error ellipses’ lying in a plane. Two or more error ellipses are clustered and then merged into a single error ellipse if the information lost in the merging process is sufficiently small. This criterion is numerically implemented and tested in a code developed for this purpose.
