Modelagens estatística para dados de sobrevivência bivariados : uma abordagem bayesiana
(Universidade Federal de São Carlos, 2017-03-31)
The frailty models are used to model the possible associations between survival times. Another alternative developed for modeling the dependence between multivariate data is the use of models based on copulas functions.

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 ...
Distribuições preditiva e implícita para ativos financeiros
(Universidade Federal de São Carlos, 2017-06-01)
We present two different approaches to obtain a probability density function for the
stock?s future price: a predictive distribution, based on a Bayesian time series model, and
the implied distribution, based on Black & ...
Modelos espaciais de captura-recaptura para populações abertas
(Universidade Federal de São Carlos, 2018-11-22)
In this thesis we propose two spatial capture-recapture models for estimation of population abundance in the open population. The proposed statistical models conform to data obtained through individual tag capture-recapture ...
Modelos de regressão para resposta binária na presença de dados desbalanceados
(Universidade Federal de São Carlos, 2019-02-22)
In binary regression, imbalanced data result from the presence of values equal to zero (or one) in a proportion that is significantly greater than the corresponding real values of one (or zero). In this work, we evaluate ...
Some extensions in measurement error models
(Universidade Federal de São Carlos, 2018-12-14)
In this dissertation, we approach three different contributions in measurement error model
(MEM). Initially, we carry out maximum penalized likelihood inference in MEM’s under the
normality assumption. The methodology ...
Alternative regression models to beta distribution under bayesian approach
(Universidade Federal de São Carlos, 2017-08-25)
The Beta distribution is a bounded domain distribution which has dominated the modeling the
distribution of random variable that assume value between 0 and 1. Bounded domain distributions
arising in various situations ...
Regressão binária usando ligações potência e reversa de potência
(Universidade Federal de São Carlos, 2017-04-07)
The aim of this dissertation is to study a family of asymmetric link functions for binary regression models under Bayesian approach. Specifically, we present the estimation of parameters of power and reversal power binary ...
Estudo do impacto da escolha do modelo para o controle de overdose na fase I dos ensaios clínicos
(Universidade Federal de São Carlos, 2018-10-03)
Escalation with overdose control proportional hazards is a Bayesian method with overdose control that estimates the maximum tolerated dose (MTD) assuming that the time a patient takes to show toxicity follows the proportional ...
Tempo de espera para a ocorrência de palavras em ensaios de Markov
(Universidade Federal de São Carlos, 2016-04-06)
Consider a sequence of independent coin flips where we denote the result of any landing for H, if coming up head, or T, otherwise. Create patterns with H's and T's, for example, HHHHH or HTHTH. How many times do we have ...
