In genetic epidemiologic studies, investigators often use generalized linear models to evaluate the relationships between a disease trait and covariates, such as one or more candidate genes or an environmental exposure. Recently, attention has turned

We applied generalized transmission disequilibrium testing (TDT) models in combined replicates 1 through 5 from each of four simulated population samples. All analyses were conducted without knowledge of the generating models. To assess power and con

In situations in which one cannot specify a single primary outcome, epidemiologic analyses often examine multiple associations between outcomes and explanatory covariates or risk factors. To compare alternative approaches to the analysis of multiple

BRCA1 is considered to be a tumor-suppressor gene, yet mutations in this gene are uncommon in sporadic breast tumors. We investigated whether mechanisms other than DNA mutations that affect the coding region might be involved in breast carcinogenesis

In skeletal research, one of the techniques available to measure bone mineralization produces compositional data, which consist of vectors of ordered proportions of bone sample in prespecified density intervals. We investigated the value of two multi

Despite theoretical and empirical evidence that the usual MLEs can be misleading in finite samples and some evidence that bias reduced estimates are less biased and more efficient, they have not seen a wide application in practice. One can obtain bia

Assessing heterogeneity in affected relative pair linkage analysis can help control type I error or identify important subgroups. We develop a method to incorporate covariates into sib-pair analysis, and hence are able to test for covariate effects o

The responses of 387 smokers and 988 nonsmokers obtained in a population-based survey in Ontario, Canada, were compared with regard to knowledge, attitudes, and predicted behavior concerning restrictions on smoking. Responses were tabulated as percen
