Publications
Two new recursive likelihood calculation methods for genetic analysisAo Yuan
National Human Genome Center, Howard University, Statistical Genetics and Bioinformatics Unit, Washington DC, USA
Hum Hered 54:82-98. 2002..These methods can also be used in other model-based analyses. These methods are implemented in G.E.M.S., the genetic epidemiology models software...
An extension of the weighted dissimilarity test to association study in familiesAo Yuan
National Human Genome Center, Department of Community Health and Family Medicine, Howard University, Washington, DC 20059, USA
Hum Genet 122:83-94. 2007..001 or lower) for association with alcoholism. Our work can serve as a guide in the design of association studies in families...
Detecting disease gene in DNA haplotype sequences by nonparametric dissimilarity testAo Yuan
National Human Genome Center, Department of Community Health and Family Medicine, Howard University, Washington, DC, USA
Hum Genet 120:253-61. 2006..Simulation studies indicate that our test statistic overcomes the weakness of the existing ones and is robust and powerful as well...
Variance components model with disequilibriaAo Yuan
National Human Genome Center, Howard University, Washington DC 20059, USA
Eur J Hum Genet 14:941-52. 2006..Simulation studies suggest that this extended model improves inference significantly over the existing models when deviations of these disequilibria are present...
A study of genetic association with electrophysiological measures related to alcoholism: GAW14 dataAo Yuan
National Human Genome Center, Howard University, Washington, DC, USA
BMC Genet 6:S126. 2005..86, respectively. These results show that the partial answer to our starting question for this brief analysis is that the NTTH phenotypes are not jointly genetically controlled. The component ntth1 displays marked genetic linkage...
A statistical framework for haplotype block inferenceAo Yuan
Statistical Genetics and Bioinformatics Unit, Howard University, Washington, DC 20059, USA
J Bioinform Comput Biol 3:1021-38. 2005..The algorithm is linear in the number of loci, instead of NP-hard for many such algorithms. We illustrate the applications of our method to both simulated and real data sets...
Identifying the susceptibility gene(s) in a set of trait-linked genes using genotype dataAo Yuan
Statistical Genetics and Bioinformatics Unit, National Human Genome Center, Howard University, Washington, DC 20059, USA
Genetics 167:1445-59. 2004..This method can be used for singleton data, relative pair data, or general pedigree data. We have applied the method to simulated data as well as a real data set; it gives satisfactory results...
Genetic network analysis by quasi-bayesian methodAo Yuan
National Human Genome Center, Howard University, 2216 Sixth Street, N W, Suite 206, Washington, DC 20059, USA
J Bioinform Comput Biol 7:175-92. 2009..This method is simple to use, permits information updating, is flexible to incorporate desired features, and has closed-form solution. Simulation studies show that the model fits the data quite well...
Bayes factor based on the trend test incorporating Hardy-Weinberg disequilibrium: more power to detect genetic associationJinfeng Xu
Department of Statistics and Applied Probability, National University of Singapore, Singapore
Ann Hum Genet 76:301-11. 2012..We discuss how to use each of them and how to specify priors. Simulation studies and applications to three GWAS are provided to illustrate their usefulness to detect nonadditive gene susceptibility in practice...
Genome scan linkage analysis comparing microsatellites and single-nucleotide polymorphisms markers for two measures of alcoholism in chromosomes 1, 4, and 7Guanjie Chen
National Human Genome Center, College of Medicine, Howard University, Washington, DC, USA
BMC Genet 6:S4. 2005..Finally, results of all SNP analyses were compared with those obtained using microsatellite markers...
Exact test of Hardy-Weinberg equilibrium by Markov chain Monte CarloAo Yuan
Statistical Genetics and Bioinformatics Unit, National Human Genome Center, Howard University, Washington, DC 20059, USA
Math Med Biol 20:327-40. 2003..To expand the family of test statistics, we consider a class of divergence measures for the departure of HWE. Examples are given as illustrations...
Detecting case-control expression quantitative trait loci using locally most powerful or maximin robust rank testsAo Yuan
National Human Genome Center, Howard University, 2216 Sixth Street NW, Washington, DC 20059, USA
Stat Med 31:887-900. 2012..We conduct simulation studies to assess their performance and use an application to real data for illustration...
A novel approach for the simultaneous analysis of common and rare variants in complex traitsAo Yuan
National Human Genome Center, Howard University, Washington DC, USA
Bioinform Biol Insights 6:1-9. 2012..We found common and rare variants associated with both traits, consistent with published results...
Semiparametric clustering method for microarray data analysisAo Yuan
National Human Genome Center, Department of Community Health and Family Medicine, Howard University, Washington, DC, USA
J Bioinform Comput Biol 6:261-82. 2008..The results show that the proposed method yields reasonable partition of the data. As an illustration, the proposed method is applied to a real microarray data set to cluster genes...
Summary of contributions to GAW15 Group 13: candidate gene association studiesMariza de Andrade
Division of Biostatistics, Department of Health Science Research, Mayo Clinic College of Medicine, 200 First Street SW, Rochester, MN 55905, USA
Genet Epidemiol 31:S110-7. 2007....
