Hello Martin Maechler and All, A simple question (I hope): How can I compute the "sum of the dissimilarities" that appears in the pam command (from the cluster package) ?
Is it the "manhattan" distance (such as the one implemented by "dist") ? I am asking since I am running clustering on a dataset. I found 7 medoids with the pam command, and from it I have the medoid to which each observation belongs to. But when I check it, I find only (about) 90% of observations has the minimum manhattan distance to the medoids that pam predicted. If this is the manhattan distance that is used, I will create some toy data to see if I can reproduce this.
