Abstract

Most reported CNVs affect less than three HapMap samples. We model these sparse CNVs by Laplace or multimodal distributions, where learning is based on variational and EM approaches. With Affymetrix SNP6 chips on the HapMap data we found novel CNVs. Moreover many known CNVs seem to be false positives.
