Modeling underreported infant mortality data with a random censoring poisson model
(Universidade Federal de Minas GeraisUFMG, 2016-02-26)
In poor and socially deprived areas, economic, social and health data are typically underreported. As a consequence, inference using the observed counts for the event of interest will be biased and risks will be underestimated. ...
Um novo teste para a hipótese de separabilidade em processos pontuais
(Universidade Federal de Minas GeraisUFMG, 2005-05-13)
In environmental risk analysis, it is common to assume the stochastic independence (or separability) between the marks associated with the random events of a spatial-temporal point process. Schoenberg (2004, Biometrics 60, ...
Exact Bayesian inference for Markov switching Cox processes
(Universidade Federal de Minas GeraisUFMG, 2015-03-02)
Statistical modelling of point patterns is an important and common problem in several applications. An important point process, and a generalisation of the Poisson process, is the Cox process, where the intensity function ...
Modelo de mistura de processos pontuais estocásticos para tempos entre eventos de serviços na Web
(Universidade Federal de Minas GeraisUFMG, 2015-05-08)
In the present work we propose a mixture of point processes models, distinct and stochastically independent, for Internet services inter-event times. One is the Self-Feeding Process (SFP) and the other is the homogeneous ...
Mortality among Brazilian Air Force Officers
(Universidade Federal de Minas GeraisUFMG, 2014-02-17)
This study aims to (1) estimate the male mortality level for the cohorts of Brazilian Air Force officers who enrolled in the military between years 1947-1960 and were observed until June 2013; (2) compare those estimates ...
Processos estocásticos na interação da luz com a matéria
(Universidade Federal de Minas GeraisUFMG, 2009-08-19)
We study and characterize the dynamics of population inversion in the Jaynes-Cummings model. Initially we analyze the less studied case of stochastic phase fluctuations in the atomfield coupling coefficient where the ...
Modelos com reparo imperfeito no R
(Universidade Federal de Minas GeraisUFMG, 2015-08-17)
Most organizations face the problem of having high costs associated with the maintenance activity. When equipment failures occur leading to unscheduled stoppages for corrective maintenance, the associated costs include ...
Análise elastoplástica de túneis pelo método dos elementos de contorno
(Universidade Federal de Minas GeraisUFMG, 1992-12-17)
In this dissertation a two-dimensional elastoplastic tunnellig analysis, using the Direct Boundary Element Method, is presented. Mikhlin's concept for the derivative of the singular integral of the inelastic term, in the ...
Influência dos fatores socioculturais, físicos, demográficos e econômicos do ambiente familiar no consumo alimentar de escolares
(Universidade Federal de Minas GeraisUFMG, 2015-03-03)
The food intake of children can be influenced by several factors, especially by those of the home environment, identified as a strong predictor of this feature. Objective: To investigate the association between sociocultural, ...
Modelos exponenciais para grafos aleatórios valorados
(Universidade Federal de Minas GeraisUFMG, 2018-05-14)
Exponential Random Graph Models (ERGM) are statistical models for network structure, which allows us to make inferences about the generating process of such structures. They are based on three main statistics: edges, k-stars ...
