Accuracy and reliability

Overall accuracy

There is not estimated for statistical reliability.

Sampling error

Not relevant for these statistics.

Non-sampling error

There is no uncertainty calculations. One source of uncertainty is that there may be more foreign-owned enterprises than those included in these statistics. Another source of uncertainty is the uncertainty that is associated with the sources of statistics. This is especially about General Enterprise Statistics.

Quality management

Statistics Denmark follows the recommendations on organisation and management of quality given in the Code of Practice for European Statistics (CoP) and the implementation guidelines given in the Quality Assurance Framework of the European Statistical System (QAF). A Working Group on Quality and a central quality assurance function have been established to continuously carry through control of products and processes.

Quality assurance

Statistics Denmark follows the principles in the Code of Practice for European Statistics (CoP) and uses the Quality Assurance Framework of the European Statistical System (QAF) for the implementation of the principles. This involves continuous decentralized and central control of products and processes based on documentation following international standards. The central quality assurance function reports to the Working Group on Quality. Reports include suggestions for improvement that are assessed, decided and subsequently implemented.

Quality assessment

The foreign-owned companies include only those it has been possible to find using above sources. There may therefore be more foreign owned enterprises than those included in the statistics of foreign owned enterprises and this may affect the statistics overall quality.

Data revision - policy

Statistics Denmark revises published figures in accordance with the Revision Policy for Statistics Denmark. The common procedures and principles of the Revision Policy are for some statistics supplemented by a specific revision practice.

Data revision practice

There may be more foreign -owned firms than those included in the statistics of foreign-owned firms. There can therefore be revisions in previously published figures.
