Initial Postings: Read and reflect on the assigned readings for the week. Then post what you thought was the most important concept(s), method(s), term(s), and/or any other thing that you felt was worthy of your understanding in each assigned textbook chapter.
Your initial post should be based upon the assigned reading for the week, so the textbook should be a source listed in your reference section and cited within the body of the text. Other sources are not required but feel free to use them if they aid in your discussion.
Also, provide a graduate-level response to each of the following questions:
- What is an instrumental variable in linear regression? How do instrumental variables improve causal inference? Please answer both of these questions and give an example of an instrumental variable.
[Your post must be substantive and demonstrate insight gained from the course material. Postings must be in the student’s own words – do not provide quotes!] [Your initial post should be at leasb0+ words and in APA format (including Times New Roman with font size 12 and double spaced).
