Package: SKAT 2.2.5

Seunggeun (Shawn) Lee

SKAT: SNP-Set (Sequence) Kernel Association Test

Functions for kernel-regression-based association tests including Burden test, SKAT and SKAT-O. These methods aggregate individual SNP score statistics in a SNP set and efficiently compute SNP-set level p-values.

Authors:Seunggeun Lee and Zhangchen Zhao, with contributions from Larisa Miropolsky and Michael Wu
