Category: Statistical methodologies
A cell is regarded as confidential, if the n largest units contribute more than k % to the cell total, e.g. n=2 and k=85 means that a cell is defined as risky if the two largest units contribute more than 85 % to the cell total. The n and k are given by the statistical authority. In some NSIs the values of n and k are confidential. http://ec.europa.eu/eurostat/ramon/statmanuals/files/SDC_Handbook.pdf Eurostat, ESSnet "Memobust", "Memobust Glossary" (part of the Memobust Handbook on Methodology of Modern Business Statistics), March 2014
