© Federal Statistical Office, Institute for Research and Development in Federal Statistics, Elmar Wein Federal Statistical Office Changes induced by the new German data editing concept 3 IT-tools and materials for the planning of data editing A test of a macro and selective editing method, development of automatic editing methods A new training concept New treatment of errors: Distinction between influential and marginal errors Replacement of the “case-view” by a “distribution-view” Introduction of more statistical analysis in the data editing process Implementation of mathematical-statistical methods in data editing processes
