Sib-pair Command: twopair

ClassAnalysis and data manipulation command
Arguments <quantitative trait>| <binary trait> <marker locus 1> <marker locus 2> <theta12>

Performs Fulker & Cardon's Haseman-Elston interval regression for first and second marker loci versus the trait using full- and half-sib relative pairs. The recombination distance between the markers theta12 must be given. Haseman-Elston regression is performed using ibd estimated at ten points in the interval.

The procedure is not implemented in the Fortran 95 version of Sib-pair.
