Maximization of an asymmetric utility function by the least squares
(2014) Yoneda, Kiyoshi; Moretti, Antonio Carlos
This note points out that a utility maximization procedure proposed in an earlier paper may be reduced to the least squares. The utility function is asymmetric in the sense that for each cue its ideal value and the permissible range are assigned in such a way that the ideal is not necessarily at the center of the range, like »a beer of 350 ml would be ideal, but acceptable if within [100, 500]«. A practical consequence of the observation is that very little programming will be needed to deploy the utility maximization since software for the least squares is widely available.
Very fast non-dominated sorting
(2014) Smutnicki, Czesław; Rudy, Jarosław; Żelazny, Dominik
A new and very efficient parallel algorithm for the Fast Non-dominated Sorting of Pareto fronts is proposed. By decreasing its computational complexity, the application of the proposed method allows us to increase the speedup of the best up to now Fast and Elitist Multi-Objective Genetic Algorithm (NSGA-II) more than two orders of magnitude. Formal proofs of time complexities of basic as well as improved versions of the procedure are presented. The provided experimental results fully confirm theoretical findings.
Selected approaches for testing asset pricing models using Polish stock market data
(Wydawnictwa AGH, 2014) Czapkiewicz, Anna; Skalna, Iwona
The main objective of this paper is to discuss alternative methods for testing the Fama-French (FF) three-factor asset pricing model. The properties of the selected methods are compared through a simulation study. The main stress is put on the behaviour of the selected methods for small samples. The parameters used in the simulation study are obtained on the basis of real data coming from the Polish stock market (Warsaw Stock Exchange). Different sample characteristics such as homoscedasticity, conditional heteroscedasticity and autocorrelation as well as heteroscedasticity are tested.
