Results of fitting SSMF model to the metabolomic dataset. (A) Results of the gap statistic for choosing a suitable number of prototypes. (B) A two-dimensional PCA projected scatter pie chart representation of the clusters. (C) The estimated prototypes with the confidence intervals. The vertical grey dashed lines separate 7 categories of variables corresponding to Table 2.
