Recommended textbook problems will be posted below. Additional exercises from previous semesters may also be posted in this site. My intention is to post solutions to all exercises on the DHW textbook, but note that many require the use of computing software. I chose R, but you are welcome to verify solutions using other software package you deem suitable (e.g. Excel). Knowledge of R is not needed for this course but you may learn more about R here.

Please email me for possible corrections to the solutions.
