K-modes indeed is the optimal procedure to use for the problem of clustering categorical data you describe. The reference for our paper is: Chaturvedi, A.D., Green, P.E. & Carroll, J.D. (2001).

From a bibliographic review I carried out about that topic, it appeared to me that a method is often used :the k-modes method. From her/his experience, could anyone confirm or deny that it is the case ? If denied, which method could be more "powerful" ? Thanks in advance. Best Regards. Arnaud. PhD Student in Acoustics.
