In affected-sib-pair (ASP) studies, parameters such as the locus-specific sibling relative risk, lambda(s), may be estimated and used to decide whether or not to continue the search for susceptibility genes. Typically, a maximum likelihood point estimate of lambda(s) is given, but since this estimat

โฆ Synopsis
Confidence intervals for relative risk parameters estimated using affected-sib-pair data are derived and evaluated for two markers showing previous evidence of linkage to bipolar illness. For D18S41 we found some evidence, and for D18S37 stronger evidence, of relative risks greater than 1, although in both cases the estimated confidence intervals for the parameters are wide.

Locus-specific sibling relative risk is often estimated using affected-sib-pair lod score analysis of affected sibships and may be used to decide whether to continue or discontinue the search for additional susceptibility genes. We showed that relative-risk estimates obtained using affected-sib-pair
The relative risk (RR) is one of the most frequently used indices to measure the strength of association between a disease and a risk factor in etiological studies or the efficacy of an experimental treatment in clinical trials. In this paper, we concentrate attention on interval estimation of RR fo
