Nick examines the problem of testing for linkage between a disease susceptibility locus and a marker locus for sib-pair data. Given a specified simple alternative for the parameters (pO, p I , p 2 ) of the multinomial distribution of (NO, N , , N2), where Nj denotes the number of sibs sharing exactl

## Abstract An improved sib‐pair test for linkage is introduced which is superior to the previously proposed tests. The test is derived from the standard chi‐squared goodness of fit statistic by restricting the alternative hypothesis to the genetically possible. Critical values are given and exact

## Abstract It has been shown that two‐locus linkage analysis can, for some two‐locus disease models, be used to detect effects at disease loci that do not reach significance in a genome scan. However, few examples exist where two‐locus linkage has been successfully used to map genes. We study the

## Abstract Holmans' possible triangle test for affected sib pairs has proven to be a powerful tool for linkage analysis. This test is a likelihood‐ratio test for which maximization is restricted to the set of possible sharing probabilities. Here, we extend the possible triangle test to take into a

Linkage analyses and association studies were employed to detect disease susceptibility loci leading to elevated Q1 levels in Problem 2B. Phenotypes were defined to be the dichotomous affection status, the quantitative value for Q1, and Q1 adjusted for covariates. The method of mod-scores (for the d

## Abstract We address the analytical problem of evaluating the evidence for linkage at a test locus while taking into account the effect of a known linked disease locus. The method we propose is a multimarker regression approach that models the identity‐by‐descent states for affected sib‐pairs at
