Aa. Todorov et al., TESTING CAUSAL HYPOTHESES IN MULTIVARIATE LINKAGE ANALYSIS OF QUANTITATIVE TRAITS - GENERAL FORMULATION AND APPLICATION TO SIBPAIR DATA, Genetic epidemiology, 15(3), 1998, pp. 263-278
We provide a general framework for the development of model-free metho
ds for the linkage analysis of multivariate phenotypic data. It is pos
sible within this framework to test both for linkage of a set of pheno
types to one or more markers and for the presence of structural relati
ons among the phenotypes themselves. This report presents the general
model, paying special attention to the assumptions that enter its form
ulation, and outlines the estimation procedures that may be used. (C)
