This month's MHRI-GHUCCTS Monthly Statistical Seminar Series will be held on Friday, March 20, 2026, from 12 PM - 1 PM. This series features Dr. Paul Kolm, Associate Director in the Center for Biostatistics, Informatics, & Data Science (CBIDS) at MedStar Health Research Institute.

The topic of this month's seminar will be about how missing data presents a potential threat to study validity. In this session, we will consider assumptions about missingness: missing completely at random (MCAR), missing at random (MAR), and not missing at random (NMAR), and how these determine methods for multiple imputation of missing values. Discussion includes older methods of imputation that are less used but may be appropriate in some situations.
