Our research concerns psychometric data coming from the Minnesota Multiphasic Personality Inventory (MMPI) test. MMPI is one of the most frequently used in clinical mental health personality tests as well as psychopathology (mental and behavioral disorders). We are developing the Copernicus system. It is a tool for the analysis of MMPI profiles of patients with mental disorders. In this system,...

A numerical approach is classically advocated (see e.g. [12]) for encoding both the information pertaining to the state of nature and the preferences on X: uncertainty is represented by a probability distribution p and preference is encoded by a utility function u : X → [0, 1] . The pair < p, u > will be called a probabilistic utility model, PU-model for short. Acts are then ranked according to...

This paper axiomatizes expected multi-utility representations of incomplete preferences under risk and under uncertainty. The von Neumann–Morgenstern expected utility model with incomplete preferences is revisited using a ‘‘constructive’’ approach, as opposed to earlier treatments that use convex analysis. © 2012 Elsevier B.V.

The calibration theorem by Rabin (2000) implies that seemingly plausible smallstake choices under risk imply implausible large-stake risk aversion. This theorem is derived based on the expected utility of wealth model. However, Cox and Sadiraj (2006) show that such implications do not follow from the expected utility of income model. One may then wonder about the implications for more applied c...

Real-time information from microposts like Twitter is useful for applications in the crisis management domain. Currently, that potentially valuable information remains mostly unused by the command staff, mainly because the sheer amount of information cannot be handled efficiently. Sentiment analysis has been shown as an effective tool to detect microposts (such as tweets) that contribute to sit...

Image database extensions for functional brain images were assessed by asking clinicians questions about (i) diagnosis confidence level before and after using the software; (ii) expected and unexpected differences between patient and control images; and (iii) an overall rating of the future usefulness of this application in an everyday clinical setting. Examining the difference image of a patie...

There exist well established models for anonymity focusing on traffic analysis, i. e., analysing properties of single messages as, e. g., timing. However there is only little work done that use linkability information, that is information about the probability that two messages have been sent by the same sender. In this paper we model information about linkability between messages as a weighted...

In this comment, I discuss the use of statistical inference in citation analysis. In a recent paper, Williams and Bornmann argue in favor of the use of statistical inference in citation analysis. I present a critical analysis of their arguments and of similar arguments provided elsewhere in the literature. My conclusion is that the use of statistical inference in citation analysis involves majo...

This paper reviews the asymptotic expansion approach based on MalliavinWatanabe Calculus in Mathematical Finance. We give the basic formulation of the asymptotic expansion approach and discuss its power and usefulness to solve important problems arisen in finance. As illustrations we use three major problems in finance and give some useful formulae and new results including numerical analyses.

This paper discusses how numerically imprecise information can be modelled and how a risk evaluation process can be elaborated by integrating procedures for numerically imprecise probabilities and utilities. More recently, representations and methods for stating and analysing probabilities and values (utilities) with belief distributions over them (second order representations) have been sugges...
