Video 5.1

If you play this video you will hear Michael Greenacre's musical rendition of the singular value decomposition (SVD), which is the basis of all the dimension-reducing methods presented in this book. The song was recorded by Gurdeep Stephens (voice) and Lisa Olive (piano) on 21 June 2011 in Victoria, BC, Canada, with animations and commentary added by Michael in Barcelona. It was presented for the first time in Michael's invited talk "Biplot Videos" at the 9th Tartu Conference on Multivariate Analysis, 28 June 2011, in Estonia.
