'In diesem Beitrag wird das Verfahren der multiplen Imputation anhand von Datensätzen aus dem International Social Survey Programme diskutiert. Da es in den meisten Variablen fehlende Werte gibt, die in vielen unterschiedlichen Kombinationen vorkommen, werden die Imputations in mehreren Schritten durchgeführt. Als erstes werden die Angaben bei den sozio-demografischen Merkmalen ersetzt, da es hier in der Regel nur relativ wenige fehlende Werte gibt. Bei Blöcken von Items werden nur deren Summenwerte geschätzt, was die Aufgabe der Imputation vereinfacht, ohne daß dabei auf wichtige Informationen verzichtet wird. Ein weiterer Vorteil dieser Vorgehensweise ist, daß die Anzahl der einzusetzenden Werte reduziert wird.' (Autorenreferat)... view less

'This paper describes an implementation of the method of multiple imputation in the database of surveys in the International Social Science Programme. Since missing values occur for most variables, with a wide range of patterns, the imputations are carried out in stages, starting with background variables which, in general, have fewer missing values. For blocks of questionnaire items only their total scores are imputed, making the imputation task manageable without substantial loss of utility of the database, and reducing the size of the data files added to the database by the imputation procedure.'
