BIOS 6312 – Modern Regression Analysis

Announcements:  The first problem set should be turned in by email to Jamie and Caroline by 6p on Thursday, February 4. Going forward, future problem sets will be due by email by the start of class on the due date (10:30a).

Syllabus: The Spring 2021 course syllabus can be found here.

Lecture notes and recordings: It is possible that not all of the below material will be covered; these notes should be treated like a textbook in which certain subsections may be skimmed or skipped entirely. For folks who are enthusiastic about performing data analysis in R, the rightmost column contains supplementary notes that walk through examples using R code. You can find links to recordings of the course lectures here (you will need the password; also, please keep in mind that technology is not always 100% reliable).

Data: You can find the data sets and documentation associated with the course here (you will need the password). Many in-class examples, and all problems sets will be based on these data sets. You are expected to read the documentation.

Exams: Previous exams are posted for practice. Current exams (with keys) will also be posted here when the time comes. Topics will not align perfectly from year to year, but the major function of the practice exam is to allow you to gain familiarity with the kinds of questions you’ll be expected to answer.
