Analysis of “Big” Real-World Health Care Data: Promises and Perils

Professor Bhramar Mukherjee to deliver the Department of Mathematics and Statistics’ annual Henry Seely White Lectures 

Using administrative patient-care data such as Electronic Health Records and medical/pharmaceutical claims for population-based scientific research has become increasingly common. With vast sample sizes leading to very small standard errors, researchers need to pay more attention to potential biases in the estimates of association parameters of interest, specifically to biases that do not diminish with increasing sample size. Of these multiple sources of biases, in this talk, we primarily focus on understanding selection bias. We present an analytical framework for understanding selection bias and arriving at bias-reduced inference using external data from a target population. We illustrate our methods via case-studies in cancer and COVID-19. We try to highlight that sampling and study design are at the heart of analysis of big data. This is joint work with many students and colleagues at the University of Michigan School of Public Health.

This is the second of two lectures in the Henry Seely White Lecture Series. The first lecture, The Data Struggle of the Unseen, is on April 22, 2024.
