Equivalent Comparisons of Information Channels
This paper constructs a static model of information acquisition when the agent does not know exactly what pieces of information he is missing. A representation of preferences over information channels and menus of lotteries is shown by adapting the model of unforeseen contingencies by Dekel et al. (2001, 2007), which is an extension of Kreps (1979, 1992). Also, characterisation of informativene...
متن کاملFinding Equivalent Rewritings in the Presence of Arithmetic Comparisons
The problem of rewriting queries using views has received significant attention because of its applications in a wide variety of datamanagement problems. For select-project-join SQL (a.k.a. conjunctive) queries and views, there are efficient algorithms in the literature, which find equivalent and maximally contained rewritings. In the presence of arithmetic comparisons (ACs) the problem becomes...
متن کاملComparisons with a Standard in Simulation Experiments
We consider the problem of comparing a finite number of stochastic systems with respect to a single system (designated as the “standard”) via simulation experiments. The comparison is based on expected performance, and the goal is to determine if any system has larger expected performance than the standard, and if so to identify the best of the alternatives. In this paper we provide two-stage e...
متن کاملComparisons between Ambient and Forced Vibration Experiments
The ambient and forced vibration techniques for testing full-scale structures are critically compared. Both methods, based on small level excitation, may be used to determine many mode shapes and frequencies of vibration and the corresponding damping values, with adequate accuracy for most purposes. The two techniques give mutually consistent results. The mode amplitudes determined by ambient a...
متن کاملUse and misuse of multiple comparisons in animal experiments.
The objective of many animal experiments is to detect meaningful relationships among treatments and associated responses. Types of comparisons of means include pairwise multiple comparisons, planned orthogonal or nonorthogonal contrasts, and orthogonal polynomials. Some procedures are appropriate only for specific types of treatment designs and specific types of objectives. Pairwise, multiple c...
