      EPI 265 Spring 2021 (2 or 3 units)

    • Homework Submission Forum

      Please post your homework in this forum. Homework is due on the Thursday evening before class by 8 pm. For each week there will be a new topic thread; your responses should be posted as a reply within the topic thread, attaching files as necessary. You may skip one assignment without penalty (please post in the forum that week to let us know not to expect it).

      We are hosting homework in the forum (instead of as assignment submissions) because there is a value in being exposed to each other's work. Seeing other people's clarity or confusion is helpful in solidifying one's own understanding of difficult concepts. You are welcome (but not required) to use this forum to start a dialogue with each other to facilitate camaraderie and learning!

    • Choose the article that you will use for the final project, and share on the forum. Due Thurs, April 22 by 8 pm. 

      Final research project write-up (from the Syllabus):

      Read recent issues of a journal in your field (e.g., Am J Epi; Epidemiology; Neurology; Pediatrics). Choose an article that addresses a research topic of interest to you using an observational study design. 

      1. Summarize the study design, sampling, and analytic plan used in the paper. Draw a DAG corresponding with the author’s implicit or explicit causal hypotheses and specify which part of the DAG they are testing in this article. Review their handling of statistical conclusion validity, internal validity and external validity. Describe what you consider the greatest weaknesses of the paper. (This should be ~2000 words.)

      2. Write the methods section for an alternative study that would address the same research topic with either a stronger design or a design that addressed the most important limitations of the initial study. (This should be ~1500-2000 words.)
