17 p, 1.3 MB Agency Contracts under Maximum-Entropy / Gutiérrez, Oscar (Universitat Autònoma de Barcelona. Departament d'Economia de l'Empresa) ; Salas-Fumás, Vicente (Universidad de Zaragoza. Departamento de Dirección y Organización de Empresas)
This article proposes the application of the maximum-entropy principle (MEP) to agency contracting (where a principal hires an agent to make decisions on their behalf) in situations where the principal and agent only have partial knowledge on the probability distribution of the output conditioned on the agent's actions. [...]

Transmission ratio distortion (TRD) is defined as the allele transmission deviation from the heterozygous parent to the offspring from the expected Mendelian genotypic frequencies. Although TRD can be a confounding factor in genetic mapping studies, this phenomenon remains mostly unknown in pigs, particularly in traditional breeds (i. [...]

Disentangling the drivers of genetic differentiation is one of the cornerstones in evolution. This is because genetic diversity, and the way in which it is partitioned within and among populations across space, is an important asset for the ability of populations to adapt and persist in changing environments. [...]

20 p, 583.3 KB Exponentiated power Maxwell distribution with quantile regression and applications / Gallardo, Diego (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Gómez, Yolanda (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática) ; Segovia, Francisco A. (Universidad de Atacama, Copiapó (Xile). Departamento de Matemática)
In this paper we introduce an extension of the power Maxwell distribution. We also discuss a reparametrized version of this model applied to quantile regression. Some properties of the model and estimation based on the maximum likelihood estimation method are studied. [...]

22 p, 1.1 MB Modified almost unbiased two-parameter estimator for the Poisson regression model with an application to accident data / Alheety, Mustafa I. (University of Anbar (Irak). Department of Mathematics,College of Education for Pure Sciences) ; Qasim, Muhammad (Jönköping University (Suècia). Department of Economics, Finance and Statistics) ; Månsson, Kristofer (Jönköping University (Suècia). Department of Economics, Finance and Statistics) ; Kibria, B. M. Golam (Florida International University. Department of Mathematics and Statistics)
Due to the large amount of accidents negatively affecting the wellbeing of the survivors and their families, a substantial amount of research is conducted to determine the causes of road accidents. This type of data come in the form of non-negative integers and may be modelled using the Poisson regression model. [...]

Department of Statistics, Institute of Exact Sciences) ; Gallardo, Diego (Universidad de Atacama (Copiapó, Xile). Departamento de Matemáticas)
In this paper, we obtain the Bartlett factor for the likelihood ratio statistic and the Bartlett-type correction factor for the score and gradient test in censored data from a Weibull distribution. The expressions derived are simple, we only have to define a few matrices. [...]

20 p, 278.3 KB A class of goodness-of-fit tests for circular distributions based on trigonometric moments / Rao Jammalamadaka, Sreenivasa (University of California Santa Barbara. Department of Statistics and Applied Probability) ; Jiménez-Gamero, María Dolores (Universidad de Sevilla. Departamento de Estadística e Investigación Operativa) ; Meintanis, Simos G.
We propose a class of goodness-of-fit test procedures for arbitrary parametric families of circular distributions with unknown parameters. The tests make use of the specific form of the characteristic function of the family being tested, and are shown to be consistent. [...]

6 p, 3.2 MB Competitive Segmentation Performance on Near-lossless and Lossy Compressed Remote Sensing Images / García-Sobrino, Joaquín (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Pinho, Armando J. (University of Aveiro. Signal Processing Laboratory) ; Serra Sagristà, Joan (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions)
Image segmentation lies at the heart of multiple image processing chains, and achieving accurate segmentation is of utmost importance as it impacts later processing. Image segmentation has recently gained interest in the field of remote sensing, mostly due to the widespread availability of remote sensing data. [...]

25 p, 1.2 MB A generalized Watterson estimator for next-generation sequencing : from trios to autopolyploids / Ferretti, Luca (Université Pierre et Marie CURIE) ; Ramos-Onsins, Sebastian (Centre de Recerca en Agrigenòmica)
Several variations of the Watterson estimator of variability for Next Generation Sequencing (NGS) data have been proposed in the literature. We present a unified framework for generalized Watterson estimators based on Maximum Composite Likelihood, which encompasses most of the existing estimators. [...]
