Assignments

  • See hands-on
  • Extra credit (4pts): For the iris data set, construct a scatter plot in the space of the two variables that contribute most to CVI, and project the canonical variate axes into this space (similar to Fig 5C on slide 14 of the lecture slides). Make sure group membership is clearly indicated by symbols and color, and add text labels to the projected CV axes. Aim for a publication quality plot (axes labeled, plot title, etc). Submit your R code.
