We hereby post a collection of data analysis tools and supporting documents:

• Assay Based Incidence Estimation Spreadsheet (.xls): Contains tools for various statistical analyses that can be performed given one or more cross sectional surveys in which a test for recent infection was applied.
•  Assay Based Incidence Estimation Spreadsheet User Guide (.pdf): Outlines the requirements for and use of the incidence estimation spreadsheet tool.
• Assay Calibration Spreadsheet (.xls): Contains tools for estimating assay characteristics for some particular types of studies.
• Assay Calibration Spreadsheet User Guide (.pdf): Outlines the requirements for and use of the calibration spreadsheet tool.

If you have any questions about this material, please direct them to one of the following:
