New families of linear and partially linear quantile regression models under reparameterized Marshall-Olkin distributions
(Universidade Federal de São Carlos, 2023-07-31)
In this dissertation, we propose families of linear and partially linear quantile regression models,
where the response variable follows a reparameterized Marshall-Olkin distribution with support
on the real line. This ...
Modelos estocásticos de transmissão para análises genéticas de características epidemiológicas
(Universidade Federal de São Carlos, 2023-08-01)
Epidemics can significantly affect animal production and generate large economic impacts.
Furthermore, current practices for treating and controlling infectious diseases in farmed animals
do not always show the desired ...
Nova classe de modelos paramétricos para análise de sistemas reparáveis
(Universidade Federal de São Carlos, 2023-01-13)
The Arithimetic Reduction of Age (ARA) model class from Doyen e Gaudoin (2004) has been
widely used in the analysis of repairable systems, whose repair effect is expressed by an arithmetic
age reduction. However, the ...
Modelos de sobrevivência induzidos por fragilidade discreta com fração de cura e riscos proporcionais
(Universidade Federal de São Carlos, 2022-10-21)
This work presents two new survival models induced by discrete frailty with unobserved heterogeneity and proportional hazards structure, for lifetime data. The first model consider the discrete frailty variable with Katz ...
Lambert-F univariate distributions for asymmetrical data
(Universidade Federal de São Carlos, 2021-12-16)
In this dissertation, we propose new univariate continuous distributions for modeling asymmetrical data. Initially, starting from a non-linear parametric transformation of an uniform random variable, we propose a new ...
Métodos de estimação baseados em modelos na presença de dados faltantes
(Universidade Federal de São Carlos, 2022-10-14)
The missing data are observations that should have been made, but were not for some reason,
thus reducing the ability to understand the nature of the phenomenon, in addition to making it
difficult to extract information ...
Estimação do número de comunidades no modelo estocástico de blocos com correção de grau
(Universidade Federal de São Carlos, 2022-12-14)
The stochastic block model (SBM) is a random graph model that splits the set of vertices into blocks, and
the probability connection between each pair of vertices depends on the blocks to which the vertices
belong. The ...
Testes bayesianos em ensaios clínicos
(Universidade Federal de São Carlos, 2022-02-22)
In this thesis, we propose two new Bayesian approaches for equivalence hypotheses testing for proportions and prove that these Bayesian hypotheses tests are equivalent. These Bayesian methodologies applied to equivalence ...
Poincaré recurrence times in stochastic mixing processes
(Universidade Federal de São Carlos, 2022-02-17)
In the context of the discrete-time stochastic processes, this thesis presents new results on Poincaré recurrence theory. After a complete review of recent results, we present a new theorem on the exponential approximations ...
Extensões do resíduo quantílico
(Universidade Federal de São Carlos, 2022-12-20)
Regression models have profound importance in analyses that aim to investigate the relationship between a dependent variable and a set of predictor variables. The diagnostic analysis is a fundamental step in validating a ...
