The CASC project team
Statistics Netherlands is the main-contractor of the CASC-project.
It bares the overall responsibilities for the project.
The main activities of Statistics Netherlands are the further development of the ARGUS software.
Anco Hundepool studied mathematics at Leyden University and subsequently he joined
Statistics Netherlands. He started his career in the department for Statistical Methods.
His main interests were seasonal adjustment, compilation of price index series and a pilot study
on purchasing power statistics. After that he was involved in the development of the Blaise system,
became a project-leader for the Abacus tabulation package and the STATview dissemination package.
Within the SDC-project, partially funded by the 4th Framework he was the project-leader for the
development of the ARGUS package for statistical disclosure control. In the
TADEQ project for the
documentation of electronic questionnaires (also partially funded by the 4th Framework) he was
responsible for the development of the TADEQ-software.
In the CASC project he is the overall project leader and continues the development of the ARGUS
Anco Hundepool presented his work on various conferences and has published in different refereed journals.
Eric Schulte Nordholt studied mathematics at the University of Utrecht and econometrics at
the Erasmus University Rotterdam. He started his career as a researcher at the Department of S
tatistical Methods of Statistics Netherlands. In 1995 he worked as a detached national expert
at the European Community Household Panel (ECHP) team of Eurostat in Luxembourg.
Subsequently he became senior researcher at the Department of employees of the division
of Socio-economic Statistics. His main interests are data editing, imputation, metadata systems,
panel data and statistical disclosure control.
Aad van de Wetering has a long career at Statistics Netherlands. After his education
he joined Statistics Netherlands and was involved in the automation from the 'stone age' of computers.
He made tabulation software for our last census (1971) and from that period he has become an expert in tabulation.
For the Blaise system he designed (with Alex van Buitenen and Anco Hundepool) the tabulation package Abacus.
After that he became involved in the StatLine project. In the 4th Framework project
TADEQ he was involved in
the development of the TADEQ software for the automatic documentation of electronic questionnaires.
His current interest is the further development of the ARGUS software.
Aad has a special interest in number theory and the Dutch language.
His favorite activity during the lunch-break is playing chess.
But after a long career at Statistics Netherlands Aad has decided that he will retire.
Indeed from the January 1st Aad will no longer work at Statistics Netherlands and so his
contribution to ARGUS has come to an end. It is a pity for ARGUS, but we are grateful
for his contribution so far.
We hope that Aad will enjoy his retirement.

Sarah Giessing studied mathematics and statistics at the Philipps University Marburg.
After graduation she joined the Statistisches Bundesamt. She works in the Department
of Mathematical Statistical Methods. She has carried out a major research project on
software packages for tabular data protection and presented the results at various
conferences and had several published papers on tabular data protection. She was involved in
two task forces at StBA 'Improving the assessment of confidentiality for tabular data' and
'Improving GHQUAR'. She occasionally represented StBA in the Committee for Statistical
Confidentiality of the European Commission and represents StBA in the task force on
methodological aspects of statistical confidentiality of this committee.
Ruth Brand acquired her graduate in economics in 1992 at the University of Hannover
with priorities in econometrics, insurance economics and labour economics. Since 1993 she was a
lecturer at the University of Hannover. From 1993 - 1995 she worked in two different research
projects: profit sharing and participation, the Hannover panel. Since 1995 she was employed at the
subdivision of statistics. Her fields in research are data protection, statistical methods and
labour dynamics. In the field of data protection she is working since 1995. Main topics are
possibilities of anonymising business data and theoretical comparisons of the different approaches.
For instance she evaluated the re-identification risks connected with disseminating data from the
Hannover Panel and the IAB-Establishment-Panel and evaluated the possibilities of anonymising
them by adding random noise in the way Sullivan/Fuller (1989) propose.
Dietz Repsilber graduated in physics. He joined LDS NRW in 1973. Apart from being
involved in several other projects concerning software and methodology development, since 1978 he
has been developing the software package GHQUAR for secondary cell suppression. Step by step, mostly
driven by user demand, he added improvements to his system. Substantial progress was made after
the international seminar on statistical confidentiality in Dublin 1992. Since 1999 he is in close
co-operation with Eurostat. On behalf of Eurostat a PC-version of GHQUAR was developed. On particular r
equest of Eurostat users he added several facilities intended to improve the usability of GHQUAR.
Diez Repsilber was involved in the StBA task force 'Improving GHQUAR'. Currently, based on the
recommendations of that task force, he is in the process of refining his package, making it
applicable to sets of linked tables. He presented his package at two international seminars
on statistical confidentiality (1992 and 1994) and had published papers (in German language)
describing his method for secondary cell suppression.
