Homework #2

  1. Much easier than the in class quizzes were.
  2. Much clearer questions than last homework, most likely because they are numeric.
  3. Weird things happen when the priors are 0.5.
  4. Big problem with this model of evaluation: no partial credit.  It's easy to have a small error in knowledge but get the problem wrong.  Usually this is made up for in automatically graded exams by asking lots of questions, so if you know 80% of the material you get 80% of the questions right.  But with few questions, you need to look at them more closely to evaluate the level of knowledge.
