Efficiency assessment of Ichino method and mean value method of selecting variables in cluster analysis

Summary/Abstract: Ichino method can be applied to variables measured on any type of scale. Pełka and Wilk examined the method but their investigation was limited to a couple of cluster structures and the criterion used was the stability of grouping based on the silhouette index. The mean value method [Fraiman et al. 2008] is a relatively new method not investigated until now in a broad simulation experiment. In the paper the results of simulation experiment are presented. The criteria used are: recall, precision and Rand index. The competing methods are HINoV and its two modifications: VSKM and VAF with clusterability index.
