We tested the script on a synthetic 100×10 dataset. The PCA scree plot (Fig. 1) showed that 3 components capture 82% of the variance. The LDA projection (Fig. 2) separated the two synthetic classes almost perfectly due to the constructed differences in means. Clustering on unlabeled data suggested an optimal k of 3. mva script
