Illness, or the medical treatment of a family member, comprises an inherent part of human life, the occurrence of which often prevents employees from attending work. This article analyses the relationship between absence from work due to illness and the amount of an individual's income. The...

Graphical games describe strategic interactions among a specified network of players. The threshold protocol game is a graphical game that models the adoption of a lesser-used product in a population when individuals benefit by using the same product. The threshold protocol game has historically...

The threshold protocol game is a graphical game that models the adoption of an idea or product through a population. There are two states players may take in the game, and the goal of the game is to motivate the state that begins in the minority to spread to every player. Here, the threshold...

Purpose This paper aims to present a systematic literature review of 176 studies relating to change management in the context of process optimization and to investigate how companies effectively use change management to optimize processes across different industrial sectors....

The purpose of the study is to determine the most relevant method of a time series analysis to identify the cyclicality in the development of regional economies. In pursuit of the goal, a comparative approach was employed, focusing on the utilization of Gross Regional Product (GRP) indicators...

The communities in a network have distinct characteristics and interrelationships. Community discovery methods based on node embedding and deep learning have surpassed spectral clustering and statistical inference as the preferred methods for handling high-dimensional network data. Community...

A time series can often be characterized using machine learning techniques, which require feature vectors as input. The quality of the feature vectors reflects the accuracy of the utilized machine learning techniques. We propose a method for combining features extracted from two popular...

Ziel der vorliegenden Webscraping-Analyse ist es, für die Betriebs- und Organisationslandschaft der Region Hannover sowie der Landkreise Hildesheim und Peine einen Überblick über die Relevanz innovativer Technologien und Konzepte zu geben. Hierfür werden die Websites ausgewertet und die...

Complementing more specific "p-value discussions", this paper presents fundamental arguments for when null hypothesis statistical significance tests (NHST) are required and appropriate. The arguments, which are paradigmatic rather than technical, are operationalised and broken down to the extent...

Despite the widespread use of graphs in empirical research, little is known about readers' ability to process the statistical information they are meant to convey ("visual inference"). We study visual inference within the context of regression discontinuity (RD) designs by measuring how...

One of the prominent types of calendar anomalies includes holiday effects, where stocks show abnormally higher mean returns on the days prior to holidays in comparison to other trading days. The current study investigates the existence of holiday effects in the stock exchanges of the Gulf...

A frequent challenge when using graphical models in applications is that the sample size is limited relative to the number of parameters to be learned. Our motivation stems from applications where one has external data, in the form of networks between variables, that provides valuable...

Der Aufsatz beschreibt das Umsatzsteuerpanel, zeigt Analysemöglichkeiten auf und diskutiert Schwächen des Datensatzes. Zudem erfolgt als Beispiel eine Analyse der Entwicklung der Unternehmensumsätze in den Jahren nach der Finanzkrise 2008/2009. In deskriptiven Statistiken wird dabei...

We propose a way to formalize the relationship between descriptive analysis and structural estimation. A researcher reports an estimate ĉ of a structural quantity of interest c that is exactly or asymptotically unbiased under some base model. The researcher also reports descriptive statistics...

In recent years, graphics have become an essential part of modern data analysis. This paper describes a system called CLOUDS which is designed to make available on inexpensive storage tube terminals a wide range of graphic tools related to data analysis, economics, and management science. The...

We present a novel technique for cardinality-constrained index-tracking, a common task in the financial industry. Our approach is based on market graph models. We model our reference indices as market graphs and express the index-tracking problem as a quadratic K-medoids clustering problem. We...

Innere Kündigung ist ein vielseitig diskutiertes und dennoch empirisch kaum untersuchtes Phänomen. Aus den wenigen Arbeiten, die das Phänomen systematisch untersuchen, konnte sich keine Operationalisierung konsequent etablieren. Daher sollte in dieser Arbeit eine Skala entwickelt werden, die...
