Regressão binária nas abordagens clássica e bayesiana
(Universidade Federal de São Carlos, 2016-12-16)
The objective of this work is to study the binary regression model under the frequentist and Bayesian approaches using the probit, logit, log-log complement, Box-Cox transformation and skewprobit as link functions. In the ...
GARMA models, a new perspective using Bayesian methods and transformations
(Universidade Federal de São Carlos, 2016-12-16)
Generalized autoregressive moving average (GARMA) models are
a class of models that was developed for extending the univariate
Gaussian ARMA time series model to a flexible observation-driven
model for non-Gaussian time ...
Mapas da transmutação : modelagem, propriedades estruturais, estimação e aplicações
(Universidade Federal de São Carlos, 2016-12-05)
Initially, we use the quadratic transmutation maps to compose a new probability
model: the transmuted log-logistic distribution. Transmutation maps are
a convenient way of constructing new distributions, in particular ...
Comparação de métodos de estimação para problemas com colinearidade e/ou alta dimensionalidade (p > n)
(Universidade Federal de São Carlos, 2016-04-29)
This paper presents a comparative study of the predictive power of four suitable regression
methods for situations in which data, arranged in the planning matrix, are very
poorly multicolinearity and / or high dimensionality, ...
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
(Universidade Federal de São Carlos, 2016-10-28)
Modelos de regressão linear heteroscedásticos com erros t-Student: uma abordagem bayesiana objetiva
(Universidade Federal de São Carlos, 2016-02-18)
In this work , we present an extension of the objective bayesian analysis made in Fonseca et al. (2008), based on Je reys priors for linear regression models with Student
t errors, for which we consider the heteroscedasticity ...
Conectividade do grafo aleatório de Erdös-Rényi e uma variante com conexões locais
(Universidade Federal de São Carlos, 2016-03-24)
We say that a graph is connected if there is a path edges between any pair of vertices.
Random graph Erd os-R enyi with n vertices is obtained by connecting each pair of vertex with probability pn 2 (0; 1) independently ...
Modelos multiestado com fragilidade
(Universidade Federal de São Carlos, 2016-03-31)
Often intermediate events provide more detailed information about the disease process or recovery, for example, and allow greater accuracy in predicting the prognosis of patients. Such non-fatal events during the course ...
