Figure 2
(a) The dendrogram for 106 powder diffraction patterns collected on a Bruker GADDS system. There are three clusters. The yellow and red groups are connected by a relatively low tie line and thus have a high similarity. The green cluster is quite distinct. (b) The corresponding MMDS plot. This reinforces the evidence from the dendrogram: the red and yellow clusters are in close proximity and almost overlapping, but the green coloured group remains separate. (c)–(e) show the silhouettes for the three clusters. The red cluster is somewhat diffuse and has six entries <0.5 (0.44–0.49), which indicates that the clustering pattern needs inspection. The green cluster has values between 0.93–0.89 and is well defined. |
