Network effects error components models
(Asociación Argentina de Economía Política, 2019)
This paper develops a random effects error components structure fornetwork data regression models. In particular, it allows for edge and triangle specific components, which serve as a basal model for modeling network ...
Two Dimensional Honeycomb Materials: Random Fields, Dissipation and Fluctuations
(2017-02-01)
In this paper, we propose a method to describe the many-body problem of electrons in honeycomb materials via the introduction of random fields which are coupled to the electrons and have a Gaussian distribution. From a ...
Buffalos milk yield analysis using random regression models
(Pagepress Publ, 2007-01-01)
Data comprising 1,719 milk yield records from 357 females (predominantly Murrah breed), daughters of 110 sires, with births from 1974 to 2004, obtained from the Programa de Melhoramento Genetic de Bubalinos (PROMEBUL) and ...

Systematic sequencing of factorial experiments as an alternative to the random order
(2017-01-01)
The current study aims to discuss the use of systematic methods to generate experimental designs with good statistical properties and low costs. The research focuses on the sequence of experiments and on analysis the results ...
Modeling and estimation of some non Gaussian random fieldsModeling and estimatión of some non gaussian random fields
(2018)
In this work, we propose two types of models for the analysis of regression and dependence of positive and continuous spatio-temporal data, and of continuous spatio-temporal data with possible asymmetry and/or heavy tails. ...
The effect of random coupling coefficients on decoherence
(World Scientific, 2010-03)
The aim of this letter is to analyze the effect on decoherence of the randomness of the coupling coefficients involved in the interaction Hamiltonian. By studying the spin-bath model with computer simulations, we show that ...
Acurácia e precisão: revendo os conceitos de forma acurada
(Universidade Federal do Paraná (UFPR), Centro Politecnico, 2009-07-01)
Accuracy concepts that involve systematic and random effects and precision, that involves only random ones, are reviewed in this paper. An objective discussion is presented based on the definitions that appear in the ...
