SOCY7708: Hierarchical Linear Modeling Spring 2016 Wednesday 1:30 – 4:00 pm O’Neill 245 Professor: Sara Moorman Office: 404 McGuinn Hall Office hours: Tuesdays 10:30 am - 11:30 am and by appointment E-mail: moormans@bc.edu About the Course This applied course on hierarchical linear modeling is designed for graduate students with a thorough knowledge of OLS regression. It will cover 2-level models for continuous, categorical, and count outcomes, 3-level models, growth curve models, and models for couple data. The goals of the course are to develop the skills necessary to identify an appropriate technique for multilevel data analysis, estimate models, conduct diagnostics, and interpret results. We will use HLM 6 to perform the analyses; no prior knowledge of this software is required. Readings Required textbook: Hox, Joop. 2010. Multilevel Analysis: Techniques and Applications (2nd ed.). ISBN: 9781848728462 Software This course requires the use of the statistical program Stata. It is available on the computers in McGuinn 410, the Sociology graduate student lounge. For use on your own computer, you have two options: (1) access the program through remote connection to apps.bc.edu, or (2) purchase the program through BC’s Research Services. As promised, we’ll also use the program HLM. You can download the free student version here: http://www.ssicentral.com/hlm/student.html Assessment Grading scale A 93 – 100% B 83 – 86% F 0 – 59% AB- 90 – 92% 80 – 82% B+ C 87 – 89% 60 – 79% SC704 Regression Models for Categorical Data Task Article presentation Project draft Peer review Presentation Final paper draft Due date For you to select April 6 April 13 May 4 May 11 page 2 of 4 Percentage of grade 20 15 20 25 20 Article Presentation (More detail to follow) In addition to being able to use hierarchical linear models in your work, it’s important that you be able to understand others’ published work that uses the technique. You will (a) sign up for a presentation topic (i.e., method we’ve learned in class) and date; (b) find a published article that uses the method, either in a peer-reviewed journal in your area or in a general Sociology journal; (c) share the article with your classmates; (d) briefly present on the article and lead a class discussion appraising its merits. Research Project (More detail on each step to follow) I find that the best way to learn statistics is to practice them on real data that mean something to you. Therefore, you’ll spend the semester producing a chunk of a journal article, including methods, results, tables, and any helpful figures. You will leave off introduction/lit review and discussion sections, except for a few paragraphs to set up the research question and draw a conclusion about it. The article is required to include one or more of the methods covered in class from February 17 through April 13. At the beginning of April, you will submit a draft of the paper. The draft has two purposes: (a) to ensure that you pace your work throughout the semester, rather than try to write the whole paper the night before it is due, and (b) to provide opportunity for my feedback on your work. As such, the update is required but not graded. If you turn it in and make a good-faith effort on it, you will receive full credit. You will also exchange your draft with a classmate and complete peer reviews for one another. I’ll match you up later in the semester based on the similarity of your topic, data, or methods. Finally, you’ll give a conference-style presentation of your project during the last class, and on May 11, submit your completed paper. Although it’s certainly not a requirement, you should seriously consider using this project as an opportunity to meet a degree requirement (e.g., area exams), prepare a conference presentation, and/or develop a submission for publication. If you’re already working on a project, I encourage you to use this course to develop it. If you’re starting from scratch, many datasets are publicly available from universities and government agencies, and many more are available to researchers through BC’s subscription to the Inter-University Consortium for Political and Social Research (ICPSR) at the University of Michigan. We’ll talk about accessing secondary data in January.
