K-means ++ is an algorithm which runs before the actual k-means and finds the best starting points for the centroids. The next item on the agenda is setting a random state.

Feb 24, 2014 · This video walks you through the essentials of cluster analysis in Stata like generating the clusters, analyzing its features with dendograms and cluster centroids and also doing ANOVA tests. generate(groupvar) provides the name of the grouping variable to be created by cluster kmeans or cluster kmedians. By default, this will be the name speciﬁed in name(). iterate(#)speciﬁes the maximum number of iterations to allow in the kmeans or kmedians clustering algorithm. The default is iterate(10000). In statistics and data mining, k-medians clustering is a cluster analysis algorithm. It is a variation of k-means clustering where instead of calculating the mean for each cluster to determine its centroid, one instead calculates the median. K-means clustering means that you start from pre-defined clusters. "Pre-defining" can happen in a number of ways. I give only an example where you already have done a hierarchical cluster analysis (or have some other grouping variable) and wish to use K-means clustering to "refine" its results (which I personally think is recommendable).

In statistics and data mining, k-medians clustering is a cluster analysis algorithm. It is a variation of k-means clustering where instead of calculating the mean for each cluster to determine its centroid, one instead calculates the median. One of the more commonly used partition clustering methods is called kmeans cluster analysis. In kmeans clustering, the user speciﬁes the number of clusters, k, to create using an iterative process. Each observation is assigned to the group whose mean is closest, and then based on that categorization, new group means are determined.
