Data Services: Workshop Series

Empower faculty and students with library and other free resources related to data research activities and practical analyses.

Workshop Series

The mission of the University of Alabama Libraries Data Services Workshop Series (DSWS) is to create an environment where faculty, students, and staff at the University of Alabama (UA) can receive training in data science research methods. The DSWS facilitates an exchange of knowledge across research disciplines and provides cutting-edge analytics training to prepare UA scholars to meet the rigorous requirements of advanced research in the 21st century. The workshops are offered by faculty members on diverse topics from introductory data visualization to practical approaches in machine learning. Whether new to data analytics or a seasoned researcher, the DSWS will provide valuable opportunities to acquire the skills requisite for data science research.

An Introduction to Time-Varying Effect Modeling (TVEM)

Regression estimates the association between variables with the assumption that these variables are static and not changing over time. However, that is not always the case in real life. How to model a variable’s trajectory that is changing over time? How to understand the fluctuation in association between two variables across time? Time-varying effect modeling (TVEM), an extension of linear regression, can be a way that additionally accounts for the time dimension without making assumptions about the shape of the trajectory (e.g. curve, linear, etc). TVEM is a tool can be used with a broad variety of data types, such as cross-sectional data, historical data, and intensive longitudinal data.

In this workshop, you will learn about:

  1. The conceptualization of TVEM
  2. Data requirement for TVEM
  3. New research questions can be examined by using TVEM
  4. How to conduct TVEM in SAS through a step-by-step example


About the Instructor:

Dr. Mengya Xia is an Assistant Professor in the Department of Psychology at The University of Alabama. She received her Ph.D. in Human Development and Family Studies from The Pennsylvania State University. Her methodological expertise includes mixture modeling, time-varying effect modeling, multilevel modeling, structural equation modeling, and dynamic system modeling. Her substantive work focuses on the transactional dynamic process between complex family systems and adolescent positive development.
