Summary The so-called Exact Test of R. A. Fisher for comparing two probabilitiesp
1 andp
2 in a Fourfold-Table with small cell frequencies is known as a UMPU-Test. But in practice the test is used in a nonrandomized,
often tabulated version.
Given a certain level of significanceα it is shown: the critical region of this nonrandomized test, referred to as “Fisher 1”, can be enlarged considerably. For
instance for all sample-size-sums up to 20 andα=0.01 the total number of points in the critical regions of “Fisher 1” is 552 whereas the analogous number of the new version
“Fisher 2” is 788. The size of tables for “Fisher 2” can be reduced considerably because the main parts of the critical regions
can be described by the aid of some Chi-square-test versions. In particular Yates’ continuity-correction turns out to be always
conservative in the above mentioned region relative to “Fisher 2” whereas this is not strictly true relative to “Fisher 1”.

A balanced game satisfies the CoMa-property if and only if the extreme points of its core are marginal vectors. In this note we prove that assignment games satisfy the CoMa-property. Journal of Economic Literature Classification Numbers: C71, C78. 相似文献

The standard refinement criteria for extensive form games, including subgame perfect, perfect, perfect Bayesian, sequential, and proper, reject important classes of reasonable Nash equilibria and accept many unreasonable Nash equilibria. This paper develops a new refinement criterion, based on epistemic game theory, that captures the concept of a Nash equilibrium that is plausible when players are rational. I call this the local best response (LBR) criterion. This criterion is conceptually simpler than the standard refinement criteria because it does not depend on out-of-equilibrium, counterfactual, or passage to the limit arguments. The LBR is also informationally richer because it clarifies the epistemic conditions that render a Nash equilibrium reasonable. The LBR criterion appears to render the traditional refinement criteria superfluous. 相似文献

This article describes the three main objectives of the European Community's programme of regulatory reform in the telecommunication sector: liberalization, the separation of regulatory and operational functions, and the realization of scale economies. Particular attention is paid to the new Directive on Open Network Provision. 相似文献
