Clustergram Bug? - Different dendrograms produced by Clustergram vs SPSS and pdist -> linkage -> dendrogram using the same parameters
显示 更早的评论
Good Afternoon,
I have tried already all different 'data processing' parameters of clustergram in order to get the same dendrogram that is obtained with pdist -> linkage -> dendrogram without any luck.
I also double-checked the results obtained by SPSS with the same data and parameteres used by pdist -> linkage -> dendrogram and the dendrograms are consistent.
Therefore I conclude is definitely something related with the clustergram class.
Could it be possible that there is a bug or something like that with that class?
To whom I should direct this question in order that it'll be further evaluated by the developers of clustergram?
Thanks in advance,
Diego

I think I have the same issue. I use pdist-linkage-dendrogram, then I use clustergram, the results are different.

I believe this is a bug and in 2013a they fixed this bug. I confirmed this by running my code on 2013a, and two function give the same cluster.
