Dear Students,
The lecture today had some material about the effect of verification bias on predictive value that is not in the text (because we had not figured it out yet). I drafted a little section that might be added to Chapter 5 of the second edition of EBD that goes over that material, to supplement the lecture.
This should be helpful with one of your Chapter 5 homework problems!
I've posted it on the website with today's lecture, but to save you time I will also attach to this forum posting.
I know this stuff is challenging! Hang in there, it will get easier! Talk it over. And come to section and lectures!
Tom
