Description: Cluster analysis for cognitive diagnosis based on the
        Asymptotic Classification Theory (Chiu, Douglas & Li, 2009;
        <doi:10.1007/s11336-009-9125-0>). Given the sample statistic of
        sum-scores, cluster analysis techniques can be used to classify
        examinees into latent classes based on their attribute
        patterns. In addition to the algorithms used to classify data,
        three labeling approaches are proposed to label clusters so
        that examinees' attribute profiles can be obtained.
