SUMMARY. In this paper we propose a dimension-reducing k-means clustering procedure based on a projection pursuit (PP) technique. The clustering structure of high-dimensional data in terms of low-dimensional projected points is analyzed, and the strong consistency of the estimates of the cluster centres and the projection orientations is shown.
