A Geometric Perspective on the Power of Principal Component Association Tests in Multiple Phenotype Studies.

Journal of the American Statistical Association

Liu Z, Lin X.
PMID: 31564761
J Am Stat Assoc. 2019;114(527):975-990. doi: 10.1080/01621459.2018.1513363. Epub 2019 Feb 26.

Joint analysis of multiple phenotypes can increase statistical power in genetic association studies. Principal component analysis, as a popular dimension reduction method, especially when the number of phenotypes is high-dimensional, has been proposed to analyze multiple correlated phenotypes. It...

Genetic Associations with Obstructive Sleep Apnea Traits in Hispanic/Latino Americans.

American journal of respiratory and critical care medicine

Cade BE, Chen H, Stilp AM, Gleason KJ, Sofer T, Ancoli-Israel S, Arens R, Bell GI, Below JE, Bjonnes AC, Chun S, Conomos MP, Evans DS, Johnson WC, Frazier-Wood AC, Lane JM, Larkin EK, Loredo JS, Post WS, Ramos AR, Rice K, Rotter JI, Shah NA, Stone KL, Taylor KD, Thornton TA, Tranah GJ, Wang C, Zee PC, Hanis CL, Sunyaev SR, Patel SR, Laurie CC, Zhu X, Saxena R, Lin X, Redline S.
PMID: 26977737
Am J Respir Crit Care Med. 2016 Oct 01;194(7):886-897. doi: 10.1164/rccm.201512-2431OC.

RATIONALE: Obstructive sleep apnea is a common disorder associated with increased risk for cardiovascular disease, diabetes, and premature mortality. Although there is strong clinical and epidemiologic evidence supporting the importance of genetic factors in influencing obstructive sleep apnea, its...

HYPOTHESIS TESTING FOR HIGH-DIMENSIONAL SPARSE BINARY REGRESSION.

Annals of statistics

Mukherjee R, Pillai NS, Lin X.
PMID: 26246645
Ann Stat. 2015 Feb;43(1):352-381. doi: 10.1214/14-AOS1279.

In this paper, we study the detection boundary for minimax hypothesis testing in the context of high-dimensional, sparse binary regression models. Motivated by genetic sequencing association studies for rare variant effects, we investigate the complexity of the hypothesis testing...

Genetic Variant Set-Based Tests Using the Generalized Berk-Jones Statistic with Application to a Genome-Wide Association Study of Breast Cancer.

Journal of the American Statistical Association

Sun R, Lin X.
PMID: 33041403
J Am Stat Assoc. 2020;115(531):1079-1091. doi: 10.1080/01621459.2019.1660170. Epub 2019 Oct 16.

Studying the effects of groups of single nucleotide polymorphisms (SNPs), as in a gene, genetic pathway, or network, can provide novel insight into complex diseases like breast cancer, uncovering new genetic associations and augmenting the information that can be...

Nonparametric Regression With Missing Outcomes Using Weighted Kernel Estimating Equations.

Journal of the American Statistical Association

Wang L, Rotnitzky A, Lin X.
PMID: 23144520
J Am Stat Assoc. 2010 Sep;105(491):1135-1146. doi: 10.1198/jasa.2010.tm08463. Epub 2012 Jan 01.

We consider nonparametric regression of a scalar outcome on a covariate when the outcome is missing at random (MAR) given the covariate and other observed auxiliary variables. We propose a class of augmented inverse probability weighted (AIPW) kernel estimating...

Genome-wide association study of neck circumference identifies sex-specific loci independent of generalized adiposity.

International journal of obesity (2005)

Liu Y, Zhang X, Lee J, Smelser D, Cade B, Chen H, Zhou H, Kirchner HL, Lin X, Mukherjee S, Hillman D, Liu CT, Redline S, Sofer T.
PMID: 33907307
Int J Obes (Lond). 2021 Jul;45(7):1532-1541. doi: 10.1038/s41366-021-00817-2. Epub 2021 Apr 27.

BACKGROUND/OBJECTIVES: Neck circumference, an index of upper airway fat, has been suggested to be an important measure of body-fat distribution with unique associations with health outcomes such as obstructive sleep apnea and metabolic disease. This study aims to study...
