俺有一组一共50个对象，想做cluster analysis来分析一下，
可是这组对象俺想交给两组不同的被试来做proximity的区分，
每个组都是99个被试，结果得到个两个50x50的proximity matrices，
数据大概看起来是酱紫，对角线上都是99，也就是被试人数：
矩阵A 矩阵B
A1 A2 A3 . . . A50 B1 B2 B3 . . . B50
A1 99 43 78 B1 99 87 23
A2 43 99 56 B2 87 99 43
A3 78 56 99 B3 23 43 99
. .
. .
A50 B50
两个矩阵都打算用increas | j****e

situation is different from yours. You can also read more about the
multidimensional scaling analysis (MDS) at the below website:

I only know about the method, with no real understanding at all. I hope it
might be helpful for you. All the best with your research!
