This dataset was collected by Eric Reichard at Indiana University-Purdue University, Indianapolis in 2013, as described in the linked article. Blue-dyed acrylic fibres were analysed by microspectrophotometry, followed by chemometric analysis on different fibre pairs to simulate "questioned vs. known" forensic comparisons. Statistical metrics were then calculated from the resultant data to assess the similarity of each pair.
PCA and LDA were carried out using Unscrambler X v10.3. Similarity metrics were calculated using the XLSTAT add-on for Excel. Also David Lewis did it all.
