Data are more precise at the aggregated level than in the details. The statistics are very detailed, but the most detailed information must be regarded as estimations, not exact values.
Overall accuracy
The data are more robust on the more aggregate levels, whereas figures for detailed commodity groups and industry groups must be interpreted with some care. For more information on accuracy and sources of error, please refer to the corresponding sections of the Documentation of Statistics for the underlying statistics. That is for RP01, RP02, RP05 National Accounts - input, output tables, for RP03 Manufacturers' purchases of goods and services, Accounts statistics for non-agricultural private sector, and for RP06 it is Energy accounts and Waste Accounts.
Sampling error
Not relevant for these statistics.
Non-sampling error
There is no uncertainty calculations, users are referred to those of the underlying 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 statistics are based on special aggregations and calculations from existing statistics. No consolidated quality assessment has been made for this, so users are referred to consult the quality assessments of the statistics used:
Accounts Statistics for non-agricultural private sector
Manufacturers' Purchases of Goods and Services
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
