Grading will be based on:
2 online quizzes (worth 20% total)
2 homework assignments (40% total)*
Participation in the weekly online meetings, engagement in discussions during the meetings and/or submission of questions via e-mail (10% of grade)
A final online exam (30% of grade)
Dates of when assignment will be due are indicated in the syllabus. There will be a grace period for late assignments (not for quizzes), but late assignments will be penalized according to the following rules:
1 day late: 10% off

3 days late: 50% off
4+ days late: no credit
Students should be familiar with generalized linear models and basic probability theory. The statistical software R will be used for illustrations and for (some of) the homework assignments. Thus, basic knowledge of R is required to be able to complete the assignments
