Abstract This paper addresses two sampling methodologies to respectively estimate the Owen value and Banzhaf–Owen for TU-games with a priori unions. Both proposals are based on stratified set of those coalitions that compatible system unions according their cardinalities. These analysed in terms theoretical properties establishment bounds absolute error from statistical point view. Finally, we ...

Extreme multi-label classification (XML) is becoming increasingly relevant in the era of big data. Yet, there no method for effectively generating stratified partitions XML datasets. Instead, researchers typically rely on provided test-train splits that, 1) aren’t always representative entire dataset, and 2) are missing many labels. This can lead to poor generalization ability unreliable perfor...

This work explores the use of statistical techniques, namely stratified sampling and cluster analysis, as powerful tools for deriving traffic properties at the flow level. Our results show that the adequate selection of samples leads to significant improvements allowing further important statistical analysis. Although stratified sampling is a well-known technique, the way we classify the data p...

In the United States, low marriage rates and high divorce rates among the poor have led policymakers to target this group for skillsand values-based interventions. The current research evaluated the assumptions underlying these interventions; specifically, the authors examined whether low-income respondents held less traditional values toward marriage, had unrealistic standards for marriage, an...

The purpose of this study was to identify and evaluate prosocial content of a local children’s television series News Six produced by WBGU-TV, Bowling Green, Ohio. A stratified random sample of 114 programs (228 news stories) broadcast between 1972-2002 was coded for story setting, theme, prosocial messages, and primary message attributes. Results of a nonfrequency content analysis indicate tha...

A major challenge in network and service level agreement (SLA) management is to provide Quality of Service (QoS) demanded by heterogeneous network applications. Online QoS monitoring plays an important role in the process by providing objective measurements that can be used for improving network design, troubleshooting and management. Online QoS monitoring becomes increasingly difficult and com...

Spammers intend to increase the PageRank of certain spam pages by creating a large number of links pointing to them. We propose a novel method based on the concept of personalized PageRank that detects pages with an undeserved high PageRank value without the need of any kind of white or blacklists or other means of human intervention. We assume that spammed pages have a biased distribution of p...

The aim of the present study is to assess how the necessary practice of professional secrecy may be a stressor for doctors, and to what extent MM (mortality and morbidity)-meetings and having a doctor as a spouse or partner, may serve as outlets for emotional charge. A postal survey was sent to a stratified sample of 780 doctors working in and outside hospitals in a health region in Norway (1.1...

The ability to monitor sugarcane expansion in Brazil, the world’s largest producer and exporter of sugar and second largest producer of ethanol, is important due to its agricultural, economic, strategic and environmental relevance. With the advent of flex fuel cars in 2003 the sugarcane area almost doubled over the last decade in the South-Central region of Brazil. Using remote sensing images, ...
