Description Usage Arguments Value References Examples
Conduct meta-analysis of variant-set association test of m variants assuming constant effects across K studies. These association statistics are typically Score vector, and a direct summation asymptotically amounts to inverse variance weighting. In practice, we typically input weighted test statistics. FE VT: (∑_kU_k)^T(∑_kU_k); FE BT: (∑_kη^TU_k)^2; FAT: adaptively combine FE VT and FE BT.
