BMC Proc 1:S53. 2007..03 for imprinting, but increase in the LOD score did not meet the required threshold to reliably identify imprinting as the correct mode of inheritance in genome-wide linkage scans...
- Model selection and Bayesian methods in statistical genetics: summary of group 11 contributions to Genetic Analysis Workshop 15Michael D Swartz
Department of Epidemiology, University of Texas M D Anderson Cancer Center, Houston, TX, USA
Genet Epidemiol 31:S96-102. 2007..These group contributions exhibit the value of framing genetic problems in terms of model selection, and highlight the impact of variable selection for gene mapping...
- The null distribution of stochastic search gene suggestion: a Bayesian approach to gene mappingMichael D Swartz
Department of Epidemiology, University of Texas M, Anderson Cancer Center, Box 301439, Houston, Texas 77230 1439, USA
BMC Proc 1:S113. 2007..In order to assess the null distribution we used the simulated data with the "answers" known...
- Finding factors influencing risk: comparing Bayesian stochastic search and standard variable selection methods applied to logistic regression models of cases and controlsMichael D Swartz
Department of Epidemiology, Unit 1340, UTMD Anderson Cancer Center, Houston, TX 77230 1439, USA
Stat Med 27:6158-74. 2008..This study shows that the Bayesian methods offer a way to use prior information to both increase power and decrease false-positive results when selecting factors to model complex disease risk...
- Pooling dietary data using questionnaires with open-ended and predefined responses: implications for comparing mean intake or estimating odds ratiosMichael D Swartz
Department of Epidemiology, The University of Texas M D Anderson Cancer Center, Houston, TX 77030, USA
Am J Epidemiol 171:682-90. 2010..Therefore, if pooling data cannot be restricted to the same type of response, inferences should focus on odds ratio estimation to minimize bias...
- Symptom clusters of pain, depressed mood, and fatigue in lung cancer: assessing the role of cytokine genesCielito C Reyes-Gibby
Department of Emergency Medicine, The University of Texas MD Anderson Cancer Center, Unit 1468, 1155 Pressler Street, Houston, TX, 77030 4009, USA
Support Care Cancer 21:3117-25. 2013..We assessed if a panel of immune-response genes may underlie the co-occurrence of severe pain, depressed mood, and fatigue and help identify patients with severe versus non-severe symptom clusters...
- Clinical signs of impending death in cancer patientsDavid Hui

Oncologist 19:681-7. 2014..A better understanding of these signs may improve the ability of clinicians to diagnose impending death. We examined the frequency and onset of 10 bedside physical signs and their diagnostic performance for impending death...
- The relative efficiency of penetrance estimators for sib pairsMichael D Swartz
Department of Statistics, Rice University, Texas A and M University, College Station, Houston, TX, USA
Hum Hered 59:61-6. 2005..We then provide plots of the asymptotic relative efficiency, enabling researchers to easily determine regions where the MOD score or segregation alone performs with comparable efficiency relative to joint segregation and linkage...
- Stochastic search gene suggestion: a Bayesian hierarchical model for gene mappingMichael D Swartz
Department of Statistics, Texas A and M University, 3143 TAMU, College Station, Texas 77843, USA

- Bayesian Hierarchical Risk Models: Nutrition, Genes, & Environment InteractionsMichael Swartz; Fiscal Year: 2007..The Bayesian methodologies proposed consider sources of variation that frequentist models do not, and can provide more comprehensive risk models. The models and techniques developed can be applied to multiple cancers. ..
