Elizabeth Tipton, associate professor of statistics at Northwestern University, led the Fall 2021 Nebraska Methodology Workshop Series Nov. 4 and 5.

The two-day event was presented by the Nebraska Academy for Methodology, Analytics and Psychometrics.

In her Nov. 4 research keynote, “Causal Generalizations: Building Connections Between Science and Policy,” Tipton reflected on her work as a statistician developing methods to improve the external validity of high internal validity designs. She discussed her design and analysis of individual field trials, as well as the collection of evidence across trials using meta-analysis.

The second workshop featured a discussion of best practices in meta-analyses and an introduction to the use of robust variance estimation. Tipton explained applications in R software using the clubSandwich and metafor packages.
