"When evaluating a pilot or demonstration program, there are risks from drawing inferences from a single test. This paper reviews the experiences of replication efforts from demonstrations using randomized controlled trials in the initial evaluation and the replications. Although replications of...

"This paper illustrates the effects of item-nonresponse in surveys on the results of multivariate statistical analysis when estimation of productivity is the task. To multiply impute the missing data a data augmentation algorithm based on a normal/Wishart model is applied. Data of the German IAB...

"Linking data from different sources can be used to compensate for the weaknesses characteristic for the single sources and therefore significantly increase the potential for analyses. This requires that linking data implies no consequences that cancel out the advantages. Considering this...

"Die Aufdeckung komplexer Zusammenhänge zwischen verschiedenen Merkmalen aus dem sozialwissenschaftlichen Forschungsbereich erfordert ein statistisches Analyseverfahren, das nicht nur die Vielzahl der erklärenden Merkmale (Datenvielfalt), sondern auch den Einfluß berücksichtigt, der von der...
