τ-ARGUS home page
τ-ARGUS is a software program designed to protect statistical tables.
It is one of the main results of the CASC-project.
After a test-phase (coordinated by IStat) version 3 was the final release of the CASC-project. However we have continued our efforts, also thanks to the ESSNet-project and at the end of the ESSNet project version 3.4.1 is available.
Major new extensions are the reading of SPSS-system files, inclusion of the audit-routine,
negative values in Modular and the generation of a-priory files.
You can get version 3.5.0 (Build 26) here.
UnZip the file in a temp-directory and run the install.bat procedure).
(15 April 2013).
For users of the SBS-format a conversion program to convert SBS-files to τ-ARGUS files
can be downloaded here
For the calculation of an optimal pattern of secondary suppressions τ-ARGUS uses a LP-solver.
Due to the complexity of the mathematical problems involved we use high quality
commercial LP-solvers. Traditionally we
use the Xpress-MP solver made by FICO.
Alternatively CPlex can be used, e.g. for those users who already have a licence for CPlex and who want to use that solver.
Although τ-ARGUS is free software (a result of a European 5th Framework project), these solvers are commercial products. You can download the τ-ARGUS software from this page, but you have to obtain a licence for one of these solvers yourself, directly from the suppliers.
All questions related to τ-ARGUS (including questions on the installation and use of these solvers) should be directed to Anco Hundepool.
