Structural Equation Modeling (Psych 711)

Tuesday and Thursday 2:30-3:30pm, room634

Fall 2013

The goal of this class is to familiarize you with path analysis and structural equation modeling. After a short introduction on multiple regression analysis, we will spend most of the semester on models in which one or more variables are considered to be both effects and causes. We will start with causal models without latent variables (path analysis) and then move on to non-causal models with latent variables (confirmatory factor analysis), and causal models with latent variables (hybrid models). We will be using the statistics software R. Please know that extensive work outside the classroom is required in order to succeed in this class (both readings and statistical analyses with data sets). I want to encourage you to participate actively in the class, as participation is one of the best predictors of student learning.

Where to take complaints about a Teaching Assistant or Course Instructor:

Occasionally, a student may have a complaint about a Teaching Assistant or course instructor. If that happens, you should feel free to discuss the matter directly with the TA or instructor. If the complaint is about the TA and you do not feel comfortable discussing it with him or her, you should discuss it with the course instructor. If you do not want to approach the instructor, make an appointment to speak to the Department Chair, Prof. Patricia Devine: .

If your complaint has to do with sexual harassment, you may also take your complaint to Vicky Lenzlinger, Administrative Program Specialist, . Her office is located on the second floor of the Psychology building, room 222.

If you believe the TA or course instructor has discriminated against you because of your religion, race, gender, sexual orientation, or ethnic background, you also may take your complaint to the Office of Equity and Diversity, room 179-A Bascom Hall, or go to: http://www.oed.wisc.edu/
