We propose a new approach to selecting the number of clusters for categorical data via the likelihood function based on Hamming distances.
Bibliographic details on Estimation of number of clusters in categorical data via distance-based likelihood function.
Based on the results, the number of clusters with the highest likelihood value is three. However, the number of clusters with the lowest AIC is two. In this.
