this paper examines whether combining generalized hyperbolic skew-t distribution, recently introduced in the field of insurance, and extreme value theory (evt) could result in a modeling of loss function that could model central value as well as extreme value in appropriate manner. the data used in this study are the amount of property damage and bodily injury covered under automobile liability...

the purpose of this research is to examine consumers’ brand value and brand loyalty toward luxury brands and current distribution channels for those brands (i.e. free standing, shopping center, specialty store, internet retailing). the population consisted of  the costumers, aged 19-39 years, who use branded apparel that is in kerman. about 200 questionnaires were distributed among the consumer...

In this paper, we generalize the parametric ∆-VaR method from portfolios with normally distributed risk factors to portfolios with elliptically distributed ones. We treat both the expected shortfall and the Value-at-Risk of such portfolios. Special attention is given to the particular case of a multivariate t-distribution.

The proliferation of artists, audiences, and participants who have the ability to create mirror copies of original digital media arts work challenges us to re-examine how value is assigned to digital media arts work. Historically, space and capital limitations restricted the public’s accessibility to artwork, but the growth of mass digital reproduction and alternative forms of art exhibition sp...

By Leah Jager∗ and Jon A. Wellner† Grinnell College and University of Washington A unified family of goodness-of-fit tests based on φ−divergences is introduced and studied. The new family of test statistics Sn(s) includes both the supremum version of the Anderson-Darling statistic and the test statistic of Berk and Jones (1979) as special cases (s = 2 and s = 1 respectively). We also introduce ...

In this comment we argue that the experimental evidence provided by Cummings et al. is not inconsistent with hypothetical referenda being an incentive compatible mechanism for eliciting economic values. Differences in response proportions between hypothetical and real referenda can be expected if the underlying distributions have equal means but differ in scale. Once rescaled, Cummings et al.’s...

The telecommunications-centric business model of mobile operators is under attack due to technological convergence in the communication and content industries. This has resulted in a plethora of academic contributions on the design of new business models and service platform architectures. However, a discussion of the challenges that operators are facing in adopting these models is lacking. We ...
