In this paper, we use the nonparametric regression method to establish estimators for credibility premiums under some principles of premium calculation. The asymptotic properties of the estimators are studied. © 2000 Elsevier Science B.V. All rights reserved.

We consider the chain ladder reserving method in a Bayesian set up, which allows for combining individual claims development data with portfolio information as for instance development patterns from industry-wide data. We derive the Bayes estimators and the credibility estimators within this Bayesian framework. We show that the credibility estimators are exact Bayesian in the case of the expone...

Social media are increasingly being used as an information source, including information related to risks and crises. The current study examines how pieces of information available in social media impact perceptions of source credibility. Specifically, participants in the study were asked to view 1 of 3 mock Twitter.com pages that varied the recency with which tweets were posted and then to rep...

Qualitative research is increasingly recognized and valued and its unique place in nursing research is highlighted by many. Despite this, some nurse researchers continue to raise epistemological issues about the problems of objectivity and the validity of qualitative research findings. This paper explores the issues relating to the representativeness or credibility of qualitative research findi...

History has shown that inaccurate assessments of credibility can result in tremendous costs to businesses and society. This study uses Signal Detection Theory (SDT) to improve the accuracy of credibility assessments through combining automated and participatory decision support. Participatory decision support is also proposed to encourage acceptance of the decision aid’s recommendation. A new h...

The Advanced Metering Infrastructure (AMI) is a set of smart meters and communication networks forming the basis of smart grid. These smart meters observe one’s energy consumption and communicate that information to customers, the local utility, and the grid. Steve McLaughlin presented his research on the security implications of the meter functionality. The penetration testing that was conduct...

Given the phenomenon of enormous observing over posting behaviors in virtual communities vis-à-vis relatively little exploration from academic, this paper investigates the importance of identity credibility under pre-interaction circumstance in virtual communities. We propose a model showing the antecedents and consequences of credibility of identity. Drawn on institution-based process, attitud...

Electronic Word of Mouth (eWOM) is information shared on the Internet about a product, which allows people to receive information from others they may not otherwise encounter. Online product reviews are a type of eWOM where a user posts a comment about a product and selects an image to represent the self. The perception of the image and the text in the product review can influence source credib...

Purpose – This paper seeks to understand how users determine credibility in the internet environment from a conceptual level and the implications of these new methods of credibility determination on internet tools (primarily software) and services. Design/methodology/approach – The author first examines the underlying reasons for increased dependence on the internet for information, using elect...
