Section outline

  • Quantitative Bias Analysis (QBA) 

    The focus of this workshop is methods for conducting quantitative bias analysis in epidemiologic research. We will first provide a brief introduction to confounding, information bias, and selection bias using causal diagrams. Next, we will discuss deterministic and probabilistic bias analysis. Dr. Mayeda will discuss examples of specific biases in her own work on determinants of cognitive decline in older adults. At the end of the workshop, participants should walk away with an understanding of the motivations behind quantitative bias analysis and how to use tools for conducting quantitative bias analysis.

    The first two hours will contain the material for which students in EPI207 are responsible; the last hour is optional for the class.

    Faculty:  Elizabeth Rose Mayeda
