Table 5.
Results of the second simulation study. The following methods were applied to the simulated data set described in Section 2.4: (1) supervised sparse clustering, (2) sparse clustering, (3) supervised clustering (Bair and Tibshirani, 2004), (4) k-means clustering on the top 3 principal component (PCA) scores. The mean number of misclassified observations (and associated standard errors) is shown for each method.
