Core Seminar Series

Core Seminars

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.

Modeling Semicontinuous Longitudinal Expenditures: A Practical Guide

Berd Core Seminars
Friday, July 12, 2019 - 01:30 at Hock Plaza 11110

Abstract: One‐part models, uncorrelated two‐part models, correlated conditional two‐part (CTP) models, and correlated marginalized two‐part (MTP) models have been proposed for longitudinal expenditures that often exhibit a large proportion of zeros and a distribution of continuous, highly right‐skewed positive values. Guidance on implementing and interpreting each of these model is...

Earning your wings: Design and Analysis of Pilot/Feasibility Studies

Abstract: Conducting pilot and/or feasibility studies can be an important pre-cursor to implementing successful randomized trials or observational studies, yet such studies can be ill-defined and are often poorly reported. This talk will review the purpose and importance of conducting pilot and feasibility studies as well as discuss important aspects...

Just Do It: An Introduction to the do-calculus of Causal Inference

Berd Core Seminars
Tuesday, May 21, 2019 - 01:00 at 11025 Hock Plaza

Abstract: The primary aim of this seminar is to introduce do-calculus and its applications. Do-calculus is a non-parametric framework for causal inference of observational data, in which graphical models (e.g. DAGs) are queried to generate probabilistic expressions for causal effects in terms of the observed data. More generally, the purpose...

Introduction to meta-analysis and network meta-analysis

Friday, March 15, 2019 - 01:30 at Hock 11025

Abstract: For evidence-based medicine, well-designed systematic reviews and (network) meta-analyses are generally considered to provide the best evidence for comparative effectiveness research and be at the top of the evidence hierarchy. Meta-analysis is a statistical technique for combining the findings from independent studies to assess the clinical effectiveness of interventions...
