One-sided con&dence intervals in the binomial, negative binomial, and Poisson distributions are considered. It is shown that the standard Wald interval su4ers from a serious systematic bias in the coverage and so does the one-sided score interval. Alternative con&dence intervals with better performance are considered. The coverage and length properties of the con&dence intervals are compared th...

TTL Translation Template Learner algorithm learns lexical level correspondences between two translation examples by using analog ical reasoning The sentences used as translation examples have similar and di erent parts in the source language which must correspond to the similar and di erent parts in the target language Therefore these corre spondences are learned as translation templates The le...

The fact that dependent variables of groundwater models are generally nonlinear functions of model parameters is shown to be a potentially signi®cant factor in calculating accurate con®dence intervals for both model parameters and functions of the parameters, such as the values of dependent variables calculated by the model. The Lagrangian method of Vecchia and Cooley [Vecchia, A.V. & Cooley, R...

In this paper, we re-visit the inference problem for interval identi…ed parameters originally studied in Imbens and Manski (2004) and later extended in Stoye (2007). We establish a new con…dence interval that is asymptotically valid under the same assumptions as in Stoye (2007). Like the con…dence interval of Stoye (2007), our new con…dence interval extends that of Imbens and Manski (2004) to a...

This paper studies the causal e¤ect of individuals’overcon…dence and bounded rationality on asset markets. To do that, we combine a new market mechanism with an experimental design, where (1) players’interaction is centered on the inferences they make about each others’ information, (2) overcon…dence in private information is controlled by the experimenter (i.e., used as a treatment), and (3) n...

Previous research indicates that economic agents believe that they perform better than others in a variety of environments. This paper investigates whether or not a similar phenomenon exists for social groups. Students from ten di¤erent student organizations were recruited to participate in an experiment. Subjects revealed their beliefs about their own performance and their group’s performance ...

Since the early 1980s, a bewildering array of methods for constructing bootstrap con"dence intervals have been proposed. In this article, we address the following questions. First, when should bootstrap con"dence intervals be used. Secondly, which method should be chosen, and thirdly, how should it be implemented. In order to do this, we review the common algorithms for resampling and methods f...

We present the sensor-fusion results obtained from measurements within the European research project ground explosive ordinance detection (GEODE) system that strives for the realisation of a vehicle-mounted, multi-sensor, anti-personnel landmine-detection system for humanitarian de-mining. The system has three sensor types: a metal detector (MD), an infrared camera (IR), and a ground penetratin...

one-way analysis of covariance is a popular and common statisticalmethod, wherein the equality of the means of several random variables whichhave a linear relationship with a random mathematical variable, is tested. inthis study, a method is presented to improve the one-way analysis of covari-ance when there is an uncertainty in accepting the statistical hypotheses. themethod deals with a fuzzy...

There is now a great deal of empirical evidence that business cycle uctuations contain asymmetries. The asymmetries found in post-war US data are inconsistent with the behavior of the US economy in the Great Depression. In a model where business cycle asymmetries are produced by rational uctuations in the con dence of investors, I examine whether this inconsistency can be explained by di erence...
