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 observations. I cannot
seem to be able to recreate that when using SAS.

Is there somebody who knows who is the person who created the function or
somebody who is knowledgeable on how the function is built?

Please let me know
thanks
