Exercises for Friday Oct 9

1. On Friday I went through the essence of Ch 5, on hierarchical models. Soon we start "the last new big thing" in the course, the world of MCMC.

2. Exercises: more, from earlier exam sets! First: stk 4020, 2004, #4 (hierarchical modelling of probabilities). Then: stk 4020, 2012, #1 (Galton). Then: stk 4020, 2004, #1 (Poisson forest).

** Extra message (appended later): Due to a couple of questions during the week I decide to start Friday Oct 9 with just a few minutes doing the book's Exercise 2.4.
