Title:	Epigenome-wide association studies without the need for cell-type composition
Creators Name:	Zou, J., Lippert, C., Heckerman, D., Aryee, M. and Listgarten, J.
Abstract:	In epigenome-wide association studies, cell-type composition often differs between cases and controls, yielding associations that simply tag cell type rather than reveal fundamental biology. Current solutions require actual or estimated cell-type composition--information not easily obtainable for many samples of interest. We propose a method, FaST-LMM-EWASher, that automatically corrects for cell-type composition without the need for explicit knowledge of it, and then validate our method by comparison with the state-of-the-art approach.
