We outline an efficient method for the reconstruction of a probability density function from the knowledge of its infinite sequence of ordinary moments. The approximate density is obtained resorting to maximum entropy technique, under the constraint of some fractional moments. The latter ones are obtained explicitly in terms of the infinite sequence of given ordinary moments. It is proved that the approximate density converges in entropy to the underlying density, so that it demonstrates to be useful for calculating expected values.
Abstract.One of the most critical decisions in a quality evaluation project is to establish the level at which to analyse the characteristics of the Web sites. This choice should be driven by the underlying goals of the evaluation. Scalability and flexibility are thus desiderable features of the models used to evaluate the quality of a Web site. In this paper we describe two separate studies of Regional Tourist Boards in the Alps that were conducted using the meta-model 2QCV3Q. Specifically, we will show that the results of the first study -based on a lightweight model -are consistent with those obtained with the more detailed heavyweight model in the second study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
