This is a 120 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 second worksheet includes an exercise. 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" at the web address http://www.stats.ox.ac.uk/~nicholls/uniq17/Interests.csv Make an MDS projection of the group preferences and identify people with similar interests to your own. Color and label the points in the projection using the variables in the data. Here is a sample solution.
