In statistical analysis systems data are stored in a database, and procedures or analysis methods, respectively, are stored in a method base. As will be shown in the present article, even in the case of a simple statistical test the detection of faulty data turns out to be deficient in weill-known statistical analysis systems like BMDP, SAS and SPSS. Suggestions are made to program methods and to design statistical analysis systems in such a way that careful error detection is possible to provide the user with more reliable results.
Statistische Auswertungssysteme speichern Daten in ihrer Datenbank und Methoden (Auswertungsprogramme) in ihrer Methodenbank. Anhand eines Beispiels wird gezeigt, daß, selbst im Falle eines einfachen statistischen Tests, die Überprüfung fehlerhafterDaten in den bekannten statistischen Auswertungssystemen BMDP, SAS und SPSS mangelhaft ist. Diese Arbeit enthält Vorschläge, wie Methoden zu programmieren und wie statistische Auswertungssysteme zu entwerfen sind, um eine bessere Fehlerprüfung zu gewährleisten, mit dem Ziel, dem Anwender vertrauenswürdigere Ergebnisse liefern zu können.
