The Biometry Research Group provides key consultations to NCI program managers and scientific decision-makers based on independent and cooperative studies using statistical analysis of biological data and mathematical and computer models.
The group plans and conducts studies in biostatistical and epidemiological methodologies and mathematical modeling of processes relevant to cancer prevention. Collaborations focus on cancer epidemiology, prevention, screening, and diagnosis. Other topics studied include randomized clinical trials, cancer biomarkers, bioinformatics, natural history models, nutritional epidemiology, and dietary assessment.
Meetings and Events
Measurement Error: Impact on Nutrition Research and Adjustment for its Effects
A primer on statistical issues and methods to analyze data that are subject to measurement error.
Interactive Diet and Activity Tracking in AARP (IDATA) Study Data
Device-based and intensive self-report physical activity and diet data with biomarkers.
Clinical Trial Randomization Tool
Maximally-Tolerated-Imbalance (MTI) Randomization is a method of creating randomized arm allocation sequences for a clinical trial. The linked website provides public access to a Trial Randomization Tool that permits creation of randomized arm allocation sequences for any real-world trial, using MTI Randomization.
The program computes sample size or power for user specified null hypothesis and alternative hypothesis parameter values for a variety of experimental designs.
