Hi folks, I've written a new package for identifying clusters of observations by means of the unsupervised learning K-means algorithm. For details see here: https://en.wikipedia.org/wiki/K-means_clustering The new package --named "kmeans" -- is currently not available at the gretl package server as it depends on a new built-in function which will not be be available before the next gretl release. However, those of you who would like to use it right now, simply need to do the following: 1. Get the latest gretl snapshot, and 2. obtain the package file (incl. the documentation and sample script) from here: https://github.com/atecon/kmeans/blob/master/src/kmeans.gfn Please report any remaining bugs on the mailing list. Best, Artur
