%X ABSTRACT In the present paper, we introduce an algorithm to classify HicksonĄ¯s compact groups of galaxies. The algorithm uses the discrimination analysis technique to determine the best set of indicators that can be used to construct the models in which the classification validity of the HicksonĄ¯s compact groups could be predicted, and thus distinguish between groups that have classification problems. We have concluded that the earlier classifications of the 92 HicksonĄ¯s compact groups of galaxies are correct
