Insbesondere verfolgt diese Studie zwei Hauptziele. Erstens wird das Ausmaß an abwasservermindernden Verfahrensinnovationen bei chemischen Unternehmensstandorten aus dem früheren Bundesgebiet für die 1990er Jahre untersucht. Diese Verfahren können extern erworben oder mit Hilfe...

Hierbei handelt es sich um einen empirischen Vergleich der Nachhaltigkeitsberichte der Unternehmen der chemischen Industrie, welche sich während der Bearbeitungszeit der Bachelorarbeit im DAX, MDAX oder SDAX befanden.

Some diverse indicators used to measure the innovation process are considered, They include those with art aggregate, and often national, focus, and rely on data from scientific publications, patents and R&D expenditures, etc. Others have a firm-level perspective, relying primarily on surveys or...

In much of applied statistics variables of interest are measured with error. In particular, regression with covariates that are subject to measurement error requires adjustment to avoid biased estimates and invalid inference. We consider two aspects of this problem. Detection Limits (DL) arise...

Estimation of flow volumes in computer networks involves the use of data that are either highly aggregated or fairly noisy. We address several conceptual and practical aspects of the use of such data for flow volume estimation in this work. The results presented are often of general statistical...

We propose a scaled linear mixed model to assess the effects of exposure and other covariates on multiple continuous outcomes. The most general form of the model allows a different exposure effect for each outcome. An important special case is a model that represents the exposure effects using a...

Two recently developed probabilistic multidimensional models for analyzing pairwise choice data are introduced, discussed in terms of their differential properties, and extended in several ways. The first one, the wandering vector model, was originally suggested by Carroll [12] and extended by...

In this article, we consider the setting where the event of interest can occur repeatedly for the same subject (i.e., a recurrent event; e.g., hospitalization) and may be stopped permanently by a terminating event (e.g., death). Among the different ways to model recurrent/terminal event data,...
