Tech Talk: Complex Models to Understand Complex Health Behaviors
Tech Talk – Complex Models to Understand Complex Health Behaviors Mediator – Zugui Zhang 12noon -1 pm
Tech Talk – Exploring the Human Pathome using Real-Work Data
Tech Talk: Exploring the Human Pathome using Real-World Data Location: CCHS or web Date: Thu: 11/01/18 12:00 PM – 1:00 PM Joseph Ycas feed your mind November 1, 2018. Pathome-wide association scans (PWAS) offer an alternative to the conventional one-disease-at-a-time paradigm. PWAS analysis displays negative, neutral, and positive associations across all diseases simultaneously without the filter […]
ACCEL Tech Talk
As part of the ACCEL Tech Talk Seminar Series, Paul Kolm, Ph.D., Director of Biostatistics at MedStar Cardiovascular Research Network, MedStar Heart and Vascular Institution, speaks on “Joint Modeling of Longitudinal and Time-To-Event Data: GFR and Hospitalization” on Thursday, Feb. 1, from noon-1 p.m. Studies that collect longitudinal data and time-to-event (survival/failure) data can analyze […]
Survival Analysis for Multiple Failure Time Data
Multiple failure-time data or multivariate survival data are frequently encountered in medical investigations. These data arise from time-to-occurrence studies when either of two or more events (failures) occur for the same subject, or from identical events occurring to related subjects such as family members or classmates. In these studies, failure times are correlated within cluster […]
Efficient Estimation and Inference in Matrix Regression with Application to Neuroimaging Data and Bioassay Data
Matrix regression is a generalization of conventional multivariate regression. It has potential important applications in contemporary complex structured data, such as data from neuroimaging studies, cross-over design analysis, and multivariate growth curve modeling, among many others. In this talk, I will propose a new enveloping approach to reduce estimation standard errors in multivariate regression and […]
Using Hurdle Models to Analyze Zero-Inflated Count Data
Many outcomes in medical research are counts of some event. For example, heart rate is expressed as a count of beats per minute, or a patient may have more than one infection during an ICU stay, or a patient may be re-hospitalized a number of times following their index hospitalization. When the counts are large, […]
Meta-Analysis: How to Really Lie with Statistics
This presentation examines controversies surrounding the validity and meaningfulness of meta-analysis. Dr. Kolm is Director of Biostatistics at Christiana Care Health System, Research Professor of Medicine at Thomas Jefferson University and Director of the Biostatistical Core of the Bridging Advanced Developments for Exceptional Rehabilitation (BADER) Consortium funded by the Department of Defense. He has over […]
What if We Ignore the Random Effects When Analyzing RNA-seq Data in a Multifactor Experiment?
Identifying differentially expressed (DE) genes between different conditions is one of the main goals of RNA-seq data analysis. Although a large amount of RNA-seq data are produced for two-group comparison with small sample sizes at early stage, more and more RNA-seq data are being produced in the setting of complex experimental designs such as split-plot […]
