In dem vorliegenden Artikel wird empirisch der Frage nachgegangen, ob eine auf Point&Figure-Charts basierende Anlagestrategie statistisch signifikant zu ökonomisch bedeutsamen Überrenditen führt. Dabei zeigt sich in den durchgeführten Simulationen, dass eine der beiden untersuchten...

In this paper the genetic algorithm is described, applications in the field of statistics are indicated and it is applied to the estimation of the parameters of a Johnson-type distribution. The convergence behaviour is analyzed with respect to the mutation probability, the kind of mutations and...

In this paper models for the prediction of matches in the German Soccer Bundesliga are estimated. In a frst step the expected difference of the number of goals is estimated on the basis of estimated abilities of the teams. Here, a focus lies on the necessity of robust parameter estimation. In a...

The Matching Distribution converges to a Poisson Distribution with lambda=1 as the parameter n converges to infinity. A generalization of the Matching Distribution is proposed. The properties of this Generalized Matching Distribution (GMD) turn out to be analogical to the case with lambda=1.

In this paper the efficient market hypothesis in its weak form and the existence of a Monday effect is examined for German stock returns. Using the first order autocorrelation coeffients, a method is developed to test for the existence of finite moments for daily returns. Therefore, simulations...

This paper considers the problem of parameter estimation when data of a random sample are given in the form of a frequency table. We give special consideration to a method that linearizes the cumulative distribution function. In that case parameters can be derived from the weighted estimation of...
