Heather's paper about PCA vs. other hidden variable inference methods in QTL mapping was published in Genome Biology

Thanks to the collaboration with Dr. Wei Li's lab at UC Irvine, Heather wrote this article to compare PCA with SVA, PEER, and HCP for hidden variable inference in molecular QTL mapping. The conclusion is that PCA outperforms the three other methods. The work was published in Genome Biology. Congratulations!
