Exercises for Thursday March 12

I'm at a workshop on sakprosa on Thursday 12th (and have to talk about "the rhetoric of science", whatever that is). Two of my PhD students are certified model selectors and ficologists, however, so Martin Jullum and Sam-Erik Walker, in some combination, will teach this Thursday, from the start of Ch 5. For exercises, work with Exercises 9 and 13 from the Nils collection.
