This was a 65 minute session on Data Mining using Multidimensional Scaling (MDS). It started with a brief presentation. We will use R. This is free high quality software tailored for Statistical Programming. Open R, open this worksheet and have a play. The worksheet includes an exercise. Before you came up to Oxford many of you filled in a Google Form which asked a number of (very superficial) questions about your Interests and Preferences. I have downloaded your answers into the spreadsheet "Interests.csv". with web address http://www.stats.ox.ac.uk/~nicholls/StatsTasterDay/Interests.csv Here is a sample solution which I used to create the MDS projection below, based on the data available after our session on Thursday.
