Announcements: These notes have undergone substantial revision to move the examples over to R, to improve some of the illustrations (since 2019, I’ve learned that .pdf and .eps win every day of the week), and to reduce overlap with notes for other courses. Material on weighted least squares, penalized regression, and bootstrapping can be found in the notes for BIOS 7345. Material on Bayesian methods can be found in the notes for BIOS 6342 and BIOS 7345.
Syllabus: The Spring 2023 syllabus can be found here.
Lecture notes: The lecture notes for this course are posted here. They are not to be copied without permission of the instructor.
