This paper describes a technique for the integration of con"dence information using Markov random "elds'models to improve the segmentation and reconstruction of three-dimensional acoustical images. A range image in which each point is associated with a reliability measure, namely, its `con"dencea, is directly provided by acoustic image formation process. In this paper, range and con"dence image...

Whereas probabilistic calibration has been a central normative concept of accuracy in previous research on interval estimates, we suggest here that normative approaches for the evaluation of judgmental estimates should consider the communicative interaction between the individuals who produce the judgments and those who receive or use them for making decisions. We analyze precision and error in...

This is an overview of tests for hypothesis testing that only rely on objective characteristics of the data generating process and do not rely on additional assumptions when making inference. In particular the methods are distribution-free, many apply to nonparametric settings. Only exact results are presented, results that can be proven for the given …nite sample. Asymptotic theory is not used...

The labour economics literature on signalling assumes workers know their own abilities. Well-settled experimental evidence contradicts that assumption: in the absence of hard facts, subjects are on average overcon ̄dent. First we show that in any equilibrium of any signalling model, overcon ̄dence cannot make players better o®. In order to obtain more detailed predictions, we then introduce a spe...

We propose identi…cation robust inference methods for structural multivariate factor models with rank restrictions. Such models involve nonlinear reduced rank restrictions whose identi…cation may raise serious non-regularities leading to the failure of standard asymptotics. First, we prove several invariance and nuisance-parameter reduction results for commonly used eigenvalue and minimum root ...

Value at Risk is a measure of risk exposure of a portfolio and is de ned as the maximum possible loss in a certain time frame, typically 1-20 days, and within a certain con dence, typically 95%. Full valuation of a portfolio under a large number of scenarios is a lengthy process. To speed it up, one can make use of the total delta vector and the total gamma matrix of a portfolio and compute a G...

Higher levels of integration have led to a generation of integrated circuits for which power dissipation and reliability are major design concerns. In CMOS circuits, both of these problems are directly related to the extent of circuit switching activity. The average number of transitions per second at a circuit node is a measure of switching activity that has been called the transition density....

Often when comparing the survival rates of individuals given either of two treatments the analysis stops with a test of the hypothesis of no treatment diierence and perhaps a plot of the two survival functions. The hypothesis test is usually a comparison of the two survival curves over the entire observational period. An alternative approach to this problem is to provide an investigator with a ...
