An improvement of the NEC criterion for assessing the number of clusters in a mixture model

The entropy criterion NEC showed good performances for choosing the number of clusters arising from a mixture model. But it was not valid to decide between one and more than one clusters.

Summary:The entropy criterion NEC showed good performances for choosing the number of clusters arising from a mixture model. But it was not valid to decide between one and more than one clusters. This note presents a natural extension of this criterion to deal with this situation. Illustrative experiments exhibit good behavior of this modified entropy criterion.
