Preisvolatilität auf landwirtschaftlichen Märkten

von Ledebur, Ernst-Oliver; Schmitz, Jochen - Bundesforschungsinstitut für Lädliche Räume, Wald … - 2011

In this paper, the development of price volatility on German agricultural markets is analyzed. The goal is to quantify … the degree of price volatility for selected German agricultural markets and determine how it evolutes over time. Where …, questions are: Was there an increase in price volatility? Did it came from the world markets? What is the impact of price …

Geldpolitik in den USA - die Fed in der Zinsfalle?

Illing, Gerhard - In: Ifo Schnelldienst 57 (2004) 06, pp. 31-37

Seit dem Einbruch der Aktienmärkte Anfang 2000 hat die Fed durch massive Liquiditätszufuhr versucht, die amerikanische Wirtschaft zu stabilisieren. Ein wesentliches Motiv war die Befürchtung, die amerikanische Wirtschaft könne in eine Liquiditätsfalle geraten. Motiviert von der...

A distribution-free test for deprivation dominance

Xu, Kuan; Osberg, L. - In: Econometric Reviews 17 (1998) 4, pp. 415-429

The Raw1sian perspective on social policy pays particular attentionto the least advantaged members of society, but how should "the least advantaged" be identified? The concept of deprivation dominance operationalizes in part the Rawlsian evaluation of the welfare of the least advantaged members...

Features and performance of some outlier detection methods

Barbato, G.; Barini, E. M.; Genta, G.; Levi, R. - In: Journal of Applied Statistics 38 (2011) 10, pp. 2133-2149

A review of several statistical methods that are currently in use for outlier identification is presented, and their performances are compared theoretically for typical statistical distributions of experimental data, considering values derived from the distribution of extreme order statistics as...

Sum-discrepancy test on pseudorandom number generators

Matsumoto, Makoto; Nishimura, Takuji - In: Mathematics and Computers in Simulation (MATCOM) 62 (2003) 3, pp. 431-442

We introduce a non-empirical test on pseudorandom number generators (prng), named sum-discrepancy test. We compute the distribution of the sum of consecutive m outputs of a prng to be tested, under the assumption that the initial state is uniformly randomly chosen. We measure its discrepancy...

Optimization of Agent-Based Models: Scaling Methods and Heuristic Algorithms

Oremland, Matthew; Laubenbacher, Reinhard - In: Journal of Artificial Societies and Social Simulation 17 (2014) 2, pp. 6-6

Questions concerning how one can influence an agent-based model in order to best achieve some specific goal are optimization problems. In many models, the number of possible control inputs is too large to be enumerated by computers; hence methods must be developed in order to find solutions that...

On the sampling distribution of Allan factor estimator for a homogeneous Poisson process and its use to test inhomogeneities at multiple scales

Serinaldi, Francesco; Kilsby, Chris G. - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 5, pp. 1080-1089

The Allan factor (AF) is a statistic widely used to assess if the rate of occurrences of an event tends to cluster and show persistence in a range of space and/or time scales. For a homogeneous Poisson process, the relationship between AF and the space/time is expected to be constant, thus...
