The Member States shall take appropriate measures to avoid any infringement of the obligation to supply the information referred to in Article 5. 3 The survey need not be carried out if the Member States have information from other appropriate sources or Member States are able to produce estimates of necessary data using statistical inference methods where some or all of the characteristics have not been observed for all the units for which the statistics are to be compiled. The information from other appropriate sources or the estimates of necessary data can only be used if they are at least equivalent to survey requirements as regards accuracy, quality and timeliness. 4 The burden on enterprises, particularly on small and medium-sized enterprises, and representativeness requirements according to Article 7 shall be taken into account by the Member States in their choice and combination of the sources and the use of estimates referred to in paragraph 3. 5 The Member States shall transmit to the Commission at its request all information, particularly concerning methodologies, needed for the application of this Regulation, and in particular, in cases where data are derived from administrative sources, all the information necessary for the evaluation of their reliability and comparability.
