Hello EVOLDIR members Tracking changes in biological systems over time requires robust statistical methodologies. Longitudinal Analysis in Biostatistics led by Md Tuhin Sheikh (Biostatistics, College of Health Solutions, Arizona State University) is now available as an on-demand streaming seminar. This on-demand seminar provides comprehensive training in advanced modeling frameworks, multilevel analysis, and missing data strategies using R. Evolutionary biologists and geneticists can apply these longitudinal methods to track phenotypic changes across generations, model evolutionary trajectories, and analyze time-series genomic data. By mastering these biostatistical tools, researchers can robustly handle missing data and hierarchical structures to uncover deeper insights into temporal biological processes. Access this seminar (https://instats.org/seminar/longitudinal-analysis-in-biostatistics) online at your convenience and we'd appreciate you sharing this with colleagues and students!
