LD score regression distinguishes confounding from polygenicity in genome-wide association studies

On 11/18, Chun Li presented a paper entitled “LD score regression distinguishes confounding from polygenicity in genome-wide association studies”.  Chun provided an overview of the model set-up, many of the assumptions of this statistical approach, and the overall contribution of this work to our understanding of these genetic models.  Chun pointed out the innovation of relating the concepts of genomic control and polygenicity in the same framework.
