XWXW

Introduction

XWXW implements the Unified Haseman-Elston method for non-parametric linkage test with quantitative traits. It optimally utilizes the information from a sib-pair. It is uniformly more powerful than both the classical H-E method and the revistited H-E method. Program GENIBD from SAGE or GeneHunter2 is required for sib-pair ibd estimation.
