Biostatistics
Biostatistics consultation encompasses study design, and the accompanying statistical analysis. The BDA biostatisticians help plan studies to ensure that research questions can be answered from a statistical point of view.
As part of the design, considerable effort is involved in estimating parameters that must be used in the calculation of sample size and power. Statistical analysis services include descriptive, inferential, and exploratory analyses, model building using multiple and multivariate techniques to estimated risk factors for various outcomes.
The BDA also provides randomization schedules for various designs, interpretation and explanation of results, and graphing of results. Besides conducting the data analyses, the biostatisticians provide advice for those who prefer to do the analysis themselves. This includes advice on selection of statistical software, as well as troubleshooting problems running statistical programs.
Our biostatisticians are expert SAS (UNIX or PC), S-Plus, and Minitab users, and are knowledgeable about other programs such as SPSS, ARCVIEW, and various sample size programs.
