Hello
I am running some k-medoids analysis to see if that algorithm will work better
on my dataset compared to the k-means I have been using so far.
When running k-means I used to specify the nstart option, equal to a certain
number, depending on how many random sets of clusters I wanted.

Carlson did a nice
job explaining what the R function is doing.
I can ask to SAS help as well for the SAS part. That is good idea!

Hello
I need to ask questions about the k-means clustering function. Mainly I would
like to know why, with the use of nstart=enough number of times, kmeans always
finds the same clustering arrangements; and this happens even when the input
dataset is sorted in different ways or I take out few o
5 matches
