Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Trust and Contracts: Empirical Evidence
信托与合同 经验证据 决策论
2023/4/19
Trust between parties should drive contract design: if parties were suspicious about each others' reaction to unplanned events, they might agree to pay higher costs of negotiation ex ante to complete ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：The impact of COVID-19 on hotel customer satisfaction: Evidence from Beijing and Shanghai in China
新冠肺炎 酒店顾客 满意度 影响
2023/5/10
The purpose of this study is to provide better service to hotel customers during the COVID-19 era. Specifically, this study focuses on understanding the changes in hotel customer satisfaction during t...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：International trade and Covid-19: City-level evidence from China's lockdown policy
国际贸易 新冠肺炎 中国封锁政策 城市证据
2023/5/16
We examines the impact of Covid-19 lockdowns on exports by Chinese cities. We use city-level export data at a monthly frequency from January 2018 through April 2020. Differences-in-differences estimat...
Response to Mease and Wyner,Evidence Contrary to the Statistical View of Boosting
Mease and Wyner Evidence Contrary Statistical View
2015/8/21
This is an interesting and thought-provoking paper. We especially appreciate the fact that the authors have supplied R code for their examples, as this allows the reader to understand and assess their...
The Future of Indirect Evidence
statistical learning experience of others Bayesian and frequentist
2015/8/20
Familiar statistical tests and estimates are obtained by the direct observation of cases of
interest: a clinical trial of a new drug, for instance, will compare the drug's e ects on a relevant set of...
Searching for a Trail of Evidence in a Maze
Detecting a chain of nodes in a network minimax detection Bayesian detection predictability profile of a stochastic process martingales exponential families of random variables
2015/6/17
Consider a graph with a set of vertices and oriented edges connecting pairs of vertices. Each vertex is associated with a random variable and these are assumed to be independent. In this setting, supp...
A MATHEMATICAL THEORY OF EVIDENCE FOR G.L.S. SHACKLE
MATHEMATICAL THEORY EVIDENCE FOR G.L.S. SHACKLE
2014/6/27
Evidence Theory is a branch of mathematics that concerns the combination of empirical evidence in an individual's mind in order to construct a coherent picture of reality. Designed to deal with unex...
Evidence for Conservatism in LHC SUSY Searches
Uncertainty estimation High Energy Physics
2012/11/22
The standard for discovery in the high energy physics community for claiming discovery of new physics is a $5\sigma$ excess in the observed signal over the estimated background. While a $3\sigma$ exce...
Improving power posterior estimation of statistical evidence
Marginal likelihood Markov chain Monte Carlo Power posteriors Statistical evidence Tempering Thermo dynamic integration
2012/11/22
The statistical evidence (or marginal likelihood) is a key quantity in Bayesian statistics, allowing one to assess the probability of the data given the model under investigation. This paper focuses o...
Approximate Interval Method for Epistemic Uncertainty Propagation using Polynomial Chaos and Evidence Theory
Approximate Interval Method Epistemic Uncertainty Propagation Evidence Theory
2011/9/29
Abstract: The paper builds upon a recent approach to find the approximate bounds of a real function using Polynomial Chaos expansions. Given a function of random variables with compact support probabi...
A case of combination of evidence in the Dempster-Shafer theory inconsistent with evaluation of probabilities
data fusion Dempster-Shafer theory evidence accumulation probability uncertainty
2011/8/22
Abstract: The Dempster-Shafer theory of evidence accumulation is one of the main tools for combining data obtained from multiple sources. In this paper a special case of combination of two bodies of e...
Experimental evidence of conformal invariance in soap film turbulent flows
Experimental evidence of conformal invariance soap film turbulent flows
2011/3/2
We present experimental evidence of statistical conformal invariance in isocontours of fluid thickness in experiments of two-dimensional turbulence using soap films. A Schlieren technique is used to v...
The Algebraic Structure of Amounts: Evidence from Comparatives
Comparatives weak islands degrees
2015/6/11
Heim [9] notes certain restrictions on quantifier intervention
in comparatives and proposes an LF-constraint to account for this. I
show that these restrictions are identical to constraints on...
Statistical measures applied to metal clusters: evidence of magic numbers
Statistical measures metal clusters magic numbers
2010/4/2
In this work, a shell model for metal clusters up to 220 valence electrons is used to obtain the fractional occupation probabilities of the electronic orbitals. Then, the calculation of a statistical ...
Evidence for a conjecture of Pandharipande
conjecture of Pandharipande enumerative geometry
2010/3/1
In his paper ``Hodge integrals and degenerate contributions'', Pandharipande studied the relationship between the enumerative geometry of certain 3-folds and the Gromov-Witten invariants. In some good...
