Core--Biometry

描述（由申请人提供）

Description (provided by applicant) The goal of the Biometry Core is to provide data management support for all projects, and to collaborate with project investigators in the development and application of statistical methods for design and analysis. This goal is achieved through the following specific aims: 1. To provide statistical design and review of clinical and laboratory studies including feasibility assessment and sample size estimation. 2. To develop procedures for data collection and to maintain computer databases for information storage and retrieval. 3. To provide statistical collaboration in the execution and analysis of all studies. 4. To interpret the statistical and biological literature relevant to all projects, and to develop new study design and data analysis procedures when required. Biometry support is required in all phases of the proposed studies. During study design the core will address statistical power and sample size issues, and will work with study investigators to establish data management procedures. Upon study completion, the core performs statistical analyses in collaboration with study I investigators. Core personnel will also prepare and assist in the preparation of manuscripts for publication. The Biometry Core continues to be used by all investigators in clinical and laboratory studies.
