Here is a copy of the text of the exercises in deJ&H and the definition of the gamma and inverse gaussian distributions.
The notes from 03.09.2015 are now available at set 2.
R Solution to S4 is now available at S4 and the scanned full solution to S4 is now uploaded to S4_derivations, since we didn't manage to go through all (a) - (e) items.
