This month's MHRI-GHUCCTS Monthly Statistical Seminar Series will be held Friday, March 21, 2025, 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 tree-based analysis assesses relationships among variables by dividing the variables into subcategories of categorical variables or “bins” for continuous variables that optimizes prediction of the outcome variable (can be categorical or continuous). This is in contrast to developing mathematical prediction models. Some advantages of tree-based models are eliminating the need for variable transformation (no assumptions about variable distribution) and allowing for missingness to be included as a category itself.
