In this paper, the authors elucidate the characteristics of the computer game Daihinmin, a popular Japanese card game that uses imperfect information. They first propose a method to extract feature values using n-gram statistics and a cluster analysis method that employs feature values. By...

Purpose The purpose of this paper is to derive crucial insights from multi-scale analysis to detect equity return co-movements between Korean and emerging Asian markets. Design/methodology/approach Wavelet correlation, wavelet coherence and wavelet clustering measures are used to uncover Korean...

The analysis of social indicators and the analysis of life quality are very important in order to know, in time, the changes of the main social and economic phenomena that characterize a society. To monitor the social system is a priority of modern societies because it helps to identify in time...

The aim of this research is to study life quality using the cluster analysis methodology. The analysis includes a number of classifing algorithms of elements into relatively homogenous groups and makes a global analysis of statistical units using a high number of characteristics. The required...

In hierarchical cluster analysis, dendrograms are used to visualize how clusters are formed. I propose an alternative graph called a "clustergram" to examine how cluster members are assigned to clusters as the number of clusters increases. This graph is useful in exploratory analysis for...
