Application of copulas to improve covariance estimation for partial least squaresGina M D'Angelo
Division of Biostatistics, Washington University School of Medicine, St Louis, MO, U S A
Stat Med 32:685-96. 2013..Simulation studies show that the proposed estimator is an improvement over the standard estimators of covariance. We illustrate the methods from the motivating example from a study in the area of Alzheimer's disease...- Bootstrapping GEE models for fMRI regional connectivityGina M D'Angelo
Division of Biostatistics, Washington University School of Medicine, 660 S Euclid Ave, St Louis, MO 63110, USA
Neuroimage 63:1890-900. 2012.... - A generalized estimating equations approach for resting-state functional MRI group analysisGina M D'Angelo
Division of Biostatistics, Washington University School of Medicine, St Louis, MO 63130, USA
Conf Proc IEEE Eng Med Biol Soc 2011:5064-7. 2011..We also compare these methods using simulation studies and show that the transition model may have better statistical properties... 
An index approach for the Cox model with left censored covariatesGina D'Angelo
Division of Biostatistics, Washington University School of Medicine, St Louis, MO 63110 1093, USA
Stat Med 27:4502-14. 2008..We illustrated the usefulness of this approach with an example for the GenIMS study examining the relationship between two inflammatory markers and survival...- Combining least absolute shrinkage and selection operator (LASSO) and principal-components analysis for detection of gene-gene interactions in genome-wide association studiesGina M D'Angelo
Division of Biostatistics, Washington University School of Medicine, 660 South Euclid Avenue, St, Louis, Missouri 63110, USA
BMC Proc 3:S62. 2009..Based on our results, the PCA-LASSO method shows promise in identifying gene-gene interactions, and, at this time we suggest using it with other conventional approaches, such as generalized linear models, to narrow down genetic signals... 
Treatment course with antidepressant therapy in late-life depressionYvette I Sheline
Department of Psychiatry, Washington University School of Medicine, St Louis, MO, USA
Am J Psychiatry 169:1185-93. 2012....- Visinin-like protein-1: diagnostic and prognostic biomarker in Alzheimer diseaseRawan Tarawneh
Department of Neurology, Washington University School of Medicine, St Louis, MO 63110, USA
Ann Neurol 70:274-85. 2011..Visinin-like protein-1 (VILIP-1) has demonstrated potential utility as a marker of neuronal injury. Here we investigate CSF VILIP-1 and VILIP-1/amyloid-β42 (Aβ42) ratio as diagnostic and prognostic markers in early AD... - APOE4 allele disrupts resting state fMRI connectivity in the absence of amyloid plaques or decreased CSF Aβ42Yvette I Sheline
Department of Psychiatry, The Knight Alzheimer s Disease Research Center, Washington University School of Medicine, St Louis, Missouri 63110, USA
J Neurosci 30:17035-40. 2010.... - YKL-40: a novel prognostic fluid biomarker for preclinical Alzheimer's diseaseRebecca Craig-Schapiro
Department of Neurology, Washington University School of Medicine, St Louis, Missouri 63110, USA
Biol Psychiatry 68:903-12. 2010..Therefore, biomarkers that detect AD pathology in its early stages and predict dementia onset and progression will be invaluable for patient care and efficient clinical trial design... - Serotonin signaling is associated with lower amyloid-β levels and plaques in transgenic mice and humansJohn R Cirrito
Department of Neurology, Washington University School of Medicine, St Louis, MO 63110, USA
Proc Natl Acad Sci U S A 108:14968-73. 2011..Cumulative time of antidepressant use within the 5-y period preceding the scan correlated with less plaque load. These data suggest that serotonin signaling was associated with less Aβ accumulation in cognitively normal individuals... - Support for the vascular depression hypothesis in late-life depression: results of a 2-site, prospective, antidepressant treatment trialYvette I Sheline
Department of Psychiatry, Washington University School of Medicine, 660 S Euclid, Box 8134, St Louis, MO 63110, USA
Arch Gen Psychiatry 67:277-85. 2010..Research on vascular depression has used 2 approaches to subtype late-life depression, based on executive dysfunction or white matter hyperintensity severity... - Alzheimer disease and cognitive reserve: variation of education effect with carbon 11-labeled Pittsburgh Compound B uptakeCatherine M Roe
Alzheimer s Disease Research Center, Washington University School of Medicine, St Louis, MO 63110, USA
Arch Neurol 65:1467-71. 2008..Design, Setting, and.. - A copula model for repeated measurements with non-ignorable non-monotone missing outcomeChangyu Shen

Stat Med 25:2427-40. 2006..The proposed method is then applied to one example from a community cohort study to demonstrate its capability to reduce bias... - Application of pattern-mixture models to outcomes that are potentially missing not at random using pseudo maximum likelihood estimationChangyu Shen
Division of Biostatistics, School of Medicine, Indiana University, 1050 Wishard Boulevard RG R4101, Indianapolis, IN 46202, USA
Biostatistics 6:333-47. 2005..We apply the proposed method to an epidemiologic cohort study to examine cognition decline among elderly...
