The use of the administrative data for the statistical production process has become a priority in the statistical system in Romania, deriving from the need to exploit information already existing in the public central administration databases and aimed at reducing the response burden of the units included in the classic statistical surveys. The Value Added Tax (VAT) dataset is one of the most important administrative data used in the production of official statistics. This report describes methods for detecting and correcting errors, validating and editing the turnover variable as it is found in the VAT administrative dataset. The statistical methods and techniques used are derived from the research literature and best practices in this field.
