Efficient bayesian methods for mixture models with genetic applications
(Universidade Federal de São Carlos, 2016-12-14)
We propose Bayesian methods for selecting and estimating di erent types of mixture models which are widely used in Genetics and Molecular Biology. We speci cally propose data-driven selection and estimation methods for a ...
Contribuições em modelos de regressão com erro de medida multiplicativo
(Universidade Federal de São Carlos, 2016-02-04)
In regression models in which a covariate is measured with error, it is common
to use structures that correlate the observed covariate with the true non-observed
covariate. Such structures are usually additive or ...
Metanálise para modelos de regressão

Programação linear aplicada a estatística
(Universidade Federal de São Carlos, 2017-11-27)
Determine probabilities for events where we have few information or intervals for probabilities is not so simple. For this we will develop concepts of linear programming, which allows us to solve, in a certain way, the ...
Métodos de Monte Carlo Hamiltoniano aplicados em modelos GARCH
(Universidade Federal de São Carlos, 2019-04-26)
One of the most important informations in financial market is variability of an asset. Several
models have been proposed in literature with a view of to evaluate this phenomenon. Among
them we have the GARCH models. This ...
Modelo geométrico de ordem k correlacionado
(Universidade Federal de São Carlos, 2019-08-29)
In this work we propose the correlated geometric distribution of order k, k≥1, with parameters π and ρ; π ∈(0,1), max{−1,−1−π π } ≤ρ < 1, as an extension of the generalized geometric distribution proposed by Philippou e ...
Modelos de mistura para avaliação de produtos e serviços
(Universidade Federal de São Carlos, 2019-12-16)
The product (or services) evaluation is a necessity in many steps of the development and release of such producs (services). The product evolution and the market share definition are two steps that evolves some kind of ...
Modelos de regressão para dados de contagem k-modificados
(Universidade Federal de São Carlos, 2020-01-21)
In this work the regression model to k-Modified family distributions is proposed. It is understood as modification, the inclusion of a parameter in the probability mass function of the traditional discrete distributions, ...
Análise teórica e computacional de processos estocásticos inspirados em sistemas biológicos.
(Universidade Federal de São Carlos, 2020-01-06)
The aim of this work is to present two methodologies based on the theoretical and computational analysis of continuous time stochastic processes inspired by biological systems, whose dynamics are influenced by the stochastic ...
Métodos de estimação em modelos de efeitos mistos não lineares de caudas pesadas
(Universidade Federal de São Carlos, 2019-12-05)
Parameter estimation in nonlinear mixed-effects models is often challenging. In this thesis,
a comparison of estimation methods for these models is proposed under a frequentist
approach. In the first study, a comparison ...
