Parity and Predictability of Competitions

What is the most competitive sport?

We present an extensive statistical analysis of the results of all sports competitions in five major sports leagues in England and the United States. We characterize the parity among teams by the variance in the winning fraction from season-end standings data and quantify the predictability of games by the frequency of upsets from game results data. We introduce a mathematical model in which th...

Competitions of magnetism and superconductivity in FeAs-based materials

Abstract. Using the numerical unrestricted Hartree-Fock approach, we study the ground state of a twoorbital model describing newly discovered FeAs-based superconductors. We observe the competition of a (0, π) mode spin-density wave and the superconductivity as the doping concentration changes. There might be a small region in the electron-doping side where the magnetism and superconductivity co...

Testing the Taylor Model Predictability for Exchange Rates in Latin America

Exchange rates forecasting performance is tested by a model which incorporates endogenous monetary policy through a Taylor rule reaction function. Other usual monetary and equilibrium empirical exchange rate models are also evaluated for comparison purposes. Predictability is tested by comparing the models to a benchmark random-walk specification. We contribute to the recent literature in many ...

The Impact of Architectural Competitions on the Improvement of the Post-Revolution Architecture in Iran

The 1979 Islamic Revolution of Iran is considered as a turning point in the contemporary architecture of the nation. There have been apexes to the eye catching architectural improvements in the three forthcoming decades after the revolution. One of the most effective isorganizing the contests in architectural that affairs has not only removed the recession in the field but has also discarded th...
