Introduction to Time-Varying Effect Modeling (TVEM) for Graduate Students and Postdoctoral Researchers

June 12,2018:tvem for grads

​We are pleased to offer the workshop, “Understanding Age-Related Changes Using the Time-Varying Effect Model”. TVEM allows researchers use several types of data to model the way associations between variables change over time. The workshop will present the concepts and applications of TVEM in order to give Penn State graduate students and postdoctoral researchers an efficient way to assess TVEM’s potential for their research. Lunch will be included.

Addressing Age-Related Change Using the Time-Varying Effect Model
PRESENTERS: Stephanie Lanza, Director of The Edna Bennett Pierce Prevention Research Center and professor of Biobehavioral Health and Ashley Linden-Carmichael, assistant research professor of Biobehavioral Health
WHEN: Tuesday, July 24, 2018, 10 a.m. – 2 p.m.
WHERE: Bennett Pierce Living Center, 110 Henderson Building

Introduction to TVEM is co-sponsored by the Social Science Research Institute (SSRI), The Methodology Center, and The Edna Bennett Pierce Prevention Research Center and is part of SSRI’s Innovative Methods Initiative. The workshop is FREE and open to all graduate students at Penn State. Registration is required and space is limited. To register, email Tammy Knepp (

The four-hour workshop will include

  • a conceptual introduction to TVEM, a highly flexible approach to estimate dynamic associations between covariates and outcomes;
  • motivating examples modeling age-related changes in substance-use behavior and its correlates;
  • open discussion of how TVEM might be applied in your research; and
  • demonstrations in SAS with sample code to modify for future use.

Who should attend?
We encourage you to register if you are a Penn State graduate student or postdoctoral researcher who wishes to learn more about the way processes unfold over time, and who is interested in addressing questions about age-related change using data from cross-sectional or panel studies.
