If you want to add one of my classes, the first day the class meets, make sure you come to the class, and I will tell you the procedure to apply for a permission number. I do not start any kind of wait list before the first day of class.
There are no required books. An optional book we will use for a couple weeks during the semester: A Guide to Everyday Economic Statistics, 7th ed., Gary E. Clayton, Giesbrecht, and Guo, McGraw-Hill Irwin Publishers, 2010.
Enrolled students will be given free access to the textbook once the semester starts.
