Cluster Analysis, Part V: Monte Carlo NMF

In this continuing series, we explore the NMath Stats functions for performing cluster analysis. (For previous posts, see Part 1 - PCA , Part 2 - K-Means, Part 3 - Hierarchical, and Part 4 - NMF.) The sample data set we're using classifies 89 single malt scotch whiskies on a five-point scale (0-4) for 12 flavor characteristics. To visualize the data set and clusterings, we make use of the free Mic...
