Acceptance RegionThe set of acceptable values defined by the edits for each record. For categorical data the acceptance region can be represented as a set of lattice points in N-Space. For numerical data it is a set of convex regions in N-Space (N-dimensions of real numbers). Also called a feasible region. Source: UNECE Data Editing Group See also: Acceptance Rule
Acceptance RuleLogical or arithmetic condition applied to a data item or data group that must be met if the data are to be considered correct. Source: UNECE Data Editing Group See also: Acceptance Region
Active FieldA data item (field) for which some values of this data item create a conflict in combination with values of other data items. Source: UNECE Data Editing Group Analysis of Correction RulesVerifying consistency of correction rule specifications, mainly in an extensive set of check and correction rules. Source: UNECE Data Editing Group Analysis of Edit RulesAn activity by which the consistency of a set of check rules is ascertained, implied (derived) check rules are created, and an economical form (reduction) of specifications of the originally large number of edit (check) rules is determined. Source: UNECE Data Editing Group Analytical EditingEdit rule proceeding from a logical reasoning. Source: UNECE Data Editing Group *ARIMA ModelsAutoRegressive Integrated Moving Average models. Source: UNECE Data Editing Group Arithmetic EditSee: Formal Edit Audit TrailA method of keeping track of changes to values in a field and the reason and source for each change. Audit trails are generally begun after the initial interview is completed. Source: UNECE Data Editing Group AutocorrectionData correction performed by the computer without human intervention. It makes particular use of redundancy. Exclusion (elimination) of incorrect records or substitution of a record or its part by data from other records or the correction base. Auto-correction is generally done according to rules that assure the final (corrected) record fails no edits. Source: UNECE Data Editing Group Automated Data AdjustmentsAutomated Data Adjustments occur as a result of computer actions. A desirable option in any system allowing computer actions is to allow for the overriding of those actions at some level. Batch data adjustment results in a file of corrected (edited/imputed) records with accompanying messages to report on the computer actions taken to make the adjustments. Source: UNECE Data Editing Group Automated Data ReviewAutomated Data Review may occur in a batch or interactive fashion. It is important to note that data entered in a heads-down fashion may later be corrected in either a batch or an interactive data review process.
