Seminar Series

The Applied Biostatistics Seminar Series consists of a series of talks with the primary purpose of furthering statistical knowledge on an applied level. Talks will focus on advances in biostatistical methods and statistical programming techniques and their translation into addressing biomedical research questions. The seminars are open to all members of the Duke community, but primarily geared toward applied statistical researchers.

Is Synthetic Data the Future of Data Sharing?

Khaled El Emam, PhD
Friday, December 18, 2020 - 01:30 at Zoom

Abstract: Data synthesis is a recent approach to create new data. The basic concept is to build a generative model characterizing the patterns in the original data, and then use the generative model to synthesize new data. Because there is no one-to-one mapping between the synthetic records and real individuals,...

SARS-CoV-2 evolution in the COVID-19 pandemic

Bette Korber, PhD
Friday, December 11, 2020 - 12:00 at Zoom

Abstract: SARS-CoV-2 has displayed very limited diversity during the 2020 pandemic, still there has been at least one change, Spike D614G, (caused by one of 4 mutations that define the G clade), that resulted in an altered phenotype. The Spike D614G change impacts infectivity, levels of the virus in the...

Beyond sample splitting: valid inference while double-dipping

Daniela Witten, PhD
Friday, November 20, 2020 - 12:00 at Zoom

Abstract: As datasets continue to grow in size, in many settings the focus of data collection has shifted away from testing pre-specified hypotheses, and towards hypothesis generation. Researchers are often interested in performing an exploratory data analysis in order to generate hypotheses, and then testing those hypotheses on the same...

Survival Analysis using a 5-STAR Approach in Randomized Clinical Trials

Devan Mehrotra, PhD
Friday, November 13, 2020 - 03:00 at Zoom

Abstract: Randomized clinical trials are often designed to assess whether a test treatment prolongs survival relative to a control treatment. Increased patient heterogeneity, while desirable for generalizability of results, can weaken the ability of common statistical approaches to detect treatment differences, potentially hampering the regulatory approval of safe and efficacious...
