Assignments and Assessment
1. Weekly Problem Sets.
There will be short problems posted approximately weekly on lecture content.
Solutions to these problems will be posted, and these will not be collected and graded.
That said, taking these problem sets seriously is important because that's where much of the
real learning takes place. Applied statistical methods is in the doing.
2. Take Home Assessments.
In addition, there will be two graded problem sets:
TH1 will take place during the week of 10/22 covering class material up through 10/18
   Details: posting on assignment page Monday 10/22 AM, due Thurs 10/25 in classroom HEWLETT201 by 2:15 PM
