Speaker: John Paul Helveston, John Paul (JP) is an Assistant Professor at George Washington University in the Department of Engineering Management and Systems Engineering. His research focuses on understanding how consumer preferences, market dynamics, and policy affect the emergence and adoption of low-carbon technologies, such as electric vehicles and renewable energy technologies. He also studies the critical relationship between the US and China in developing and mass producing these technologies. He has expertise in discrete choice modeling, conjoint analysis, exploratory data analysis, interview-based research methods, and the R programming language. He speaks fluent Mandarin Chinese and has conducted extensive fieldwork in China. He is also an accomplished violinist and swing dancer. John holds a Ph.D. and M.S. in Engineering and Public Policy from Carnegie Mellon University and a B.S. in Engineering Science and Mechanics (ESM) from Virginia Tech.


Description: Choice based conjoint (CBC) experiments are a critical tool for measuring preferences, yet most practitioners rely on closed source enterprise software to design and implement their survey experiments. This presentation will demonstrate an open source framework for implementing CBC experiments in R. The framework includes designing and testing the experiment with the cbcTools package, implementing the survey with the formr.org survey platform, and modeling results with the logitr package. Combined, the three tools offer a free and fully open source approach to the entire CBC experiment workflow. The framework is also quite flexible and can be integrated into workflows that use enterprise software with relative ease.

Introduction to Propensity Score Analysis with R workshop

Learn how to use propensity score analysis in R! Join our workshop on Introduction to Propensity Score Analysis with R which is a part of our workshops for Ukraine series. 


Here’s some more info: 

Title: Introduction to Propensity Score Analysis with R

Date: Thursday, July 6th, 18:00 – 20:00 CEST (Rome, Berlin, Paris timezone)

Speaker: Dr. Jason Bryer is currently an Assistant Professor and Associate Director in the Data Science and Information Systems department at the City University of New York. He is currently the Principal Investigator of the FIPSE ($3 million #P116F150077) and IES funded ($3.8 million R305A210269) Diagnostic Assessment and Achievement of College Skills (DAACS), which is a suite of technological and social supports designed to optimize student learning. Dr. Bryer’s other research interests include quasi-experimental designs with an emphasis on propensity score analysis, data systems to support formative assessment, and the use of open source software for conducting reproducible research. He is the author of over a dozen R packages, including three related to conducting propensity score analyses. When not crunching numbers, Jason is a wedding photographer and proud dad to three boys.

Description: The use of propensity score methods (Rosenbaum & Rubin, 1983) for estimating causal effects in observational studies or certain kinds of quasi-experiments has been increasing in the social sciences (Thoemmes & Kim, 2011) and in medical research (Austin, 2008) in the last decade. Propensity score analysis (PSA) attempts to adjust selection bias that occurs due to the lack of randomization. Analysis is typically conducted in two phases where in phase I, the probability of placement in the treatment is estimated to identify matched pairs or clusters so that in phase II, comparisons on the dependent variable can be made between matched pairs or within clusters. R (R Core Team, 2012) is ideal for conducting PSA given its wide availability of the most current statistical methods vis-à-vis add-on packages as well as its superior graphics capabilities.

This workshop will provide participants with a theoretical overview of propensity score methods as well as illustrations and discussion of PSA applications. Methods used in phase I of PSA (i.e. models or methods for estimating propensity scores) include logistic regression, classification trees, and matching. Discussions on appropriate comparisons and estimations of effect size and confidence intervals in phase II will also be covered. The use of graphics for diagnosing covariate balance as well as summarizing overall results will be emphasized.

Introduction to Mixed-effects Models in R workshop

Learn how to use mixed-effects models in R! Join our workshop on Introduction to Mixed-effects Models in R which is a part of our workshops for Ukraine series. 


Here’s some more info: 


Title: Introduction to Mixed-effects Models in R

Date: Thursday, June 22nd, 18:00 – 20:00 CEST (Rome, Berlin, Paris timezone)

Speaker: Philip Leftwich is an Associate Professor of Genetics and Data Science at the University of East Anglia, Norwich, UK. He teaches R programming and statistics on various modules and workshops at undergraduate and postgraduate levels. His research interests include genetics, genomics and synthetic biology as tools to help combat agricultural and disease-carrying insect pests.

Description: Mixed-effects models are indispensable in analyzing data with hierarchical or nested structures. Unlike traditional linear regression models, mixed-effects models account for both fixed effects (applying to the entire population) and random effects (varying across groups). This unique capability allows researchers to examine how individual and group-level factors work together simultaneously, providing a comprehensive understanding of the data. In fields like social sciences, education, biology, and economics, where hierarchical data is prevalent, mixed-effects models significantly enhance the precision and reliability of statistical analyses. Mastering these models empowers researchers to extract valuable insights from complex datasets effectively.

In this introductory workshop, we will cover the basics of analyzing hierarchical data. Participants will learn about the difference between fixed and random effects, model formulation, estimation, and interpretation. We will discuss assumptions, model comparison and selection, practical implementation with R, and model validation. We will work through real-world examples to showcase the applications and benefits of mixed-effects models in various fields.
