This week on The Genetics Podcast, Patrick is joined by Dr. Bin Yu, CDSS Chancellor’s Distinguished Professor at UC Berkeley. They discuss how different statistical approaches, from linear models to random forests, can be used to study complex genetic traits, recent findings on epistasis in cardiomyopathy, and how improving robustness and reproducibility can lead to more reliable scientific conclusions.
