Monte-Carlo simula- tion and test of IMOX data indicate that clustering tendency test based on the model of Hopkins statistic with sphere-rectangle window is power- ful if patterns within cluster are closed together and well separated be- tween clusters.

• Monte-Carlo模拟结果和对IMOX数据的实际检验说明,如果聚内是致密的,聚间是良好分开的,那么以Hopkins统计量和球-矩形窗口为模型建立的聚类趋势检验是有效的。
