Analytical Derivations of New Specifications for Stochastic Frontiers with Applications
In this paper, we propose the analytical derivations of new specifications for the stochastic frontier (SF) approach. In order to avoid some limitations of the traditional SF method, we introduce dependence between the two error components through copula

A Viable Approach to Mitigating Irreproducibility
In a recent article, Trafimow suggested the usefulness of imagining an ideal universe where the only difference between original and replication experiments is the operation of randomness.

The Process of price formation and the skewness of asset returns [PDF]
Distributions of assets returns exhibit a slight skewness. In this note we show that our model of endogenous price formation \cite{Reimann2006} creates an asymmetric return distribution if the price dynamics are a process in which consecutive trading ...

The visual reaction time distribution in the tasks with different demands on information processing
Background:Reaction tests are a part of the neuropsychological assessment of the individual. The design of these tests and selection of the appropriate measures of reaction time (RT) should come out from the distribution qualities of RTs.

Skew Randi�� Matrix and Skew Randi�� Energy
Let $G$ be a simple graph with an orientation $ $, which assigns to each edge a direction so that $G^ $ becomes a directed graph. $G$ is said to be the underlying graph of the directed graph $G^ $. In this paper, we define a weighted skew adjacency matrix with Rand weight, the skew Randi matrix ${\bf R_S}(G^ )$, of $G^ $ as the real skew ...

Detection of focal electroencephalogram signals using higher-order moments in EMD-TKEO domain
Detection of epileptogenic focus based on electroencephalogram (EEG) signal screening is an important pre-surgical step to remove affected regions inside the human brain.

A class of optimal tests for symmetry based on local Edgeworth approximations [PDF]
The objective of this paper is to provide, for the problem of univariate symmetry (with respect to specified or unspecified location), a concept of optimality, and to construct tests achieving such optimality.

Realizou-se este trabalho com o objetivo de determinar um tamanho amostral ótimo para as estatísticas univariadas de assimetria e curtose (z1 e z2) que, neste caso, foram adaptadas para o caso multivariado, e as estatísticas multivariadas de assimetria e

Weighing the Cosmological Energy Contents with Weak Gravitational Lensing [PDF]
Bernardeau et al. (1997), using perturbation theory, showed that the skewness of the large-scale lensing-convergence, or projected mass density, could be used to constrain $\Omega_m$, the matter content of the universe.

Importance of the first thinning in young mixed Norway spruce and European beech stands
Experimental results from the first thinning in mixed stands are not broadly experienced by forestry practice. To extend the experience with the thinning of a mixed stand, we studied thinned and unthinned mixtures of Norway spruce with European beech on ...
