Hi,
I am clustering objects using the agnes() function and the UPGMA
clustering method (function = average). Everything works well, but
apparently something is wrong with the dendrogram. For example:
x-c(102,102.1,112.5,113,100.3,108.2,101.1,104,105.5,106.3)
Does R implements Pseudo-F-Statistics Clustering ?
Vogel and Wong derived a formula to evaluate the best clusters number through
such a method.
Silhouette metod only provides an average evaluation.
Thank you very much.
