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 ...
Modelagem conjunta de dados longitudinais e de sobrevivência para avaliação de desfechos clínicos do parto
(Universidade Federal de São Carlos, 2018-12-06)
As most pregnancy-related deaths and morbidities are clustered around the time of child birth, the quality of care during this period is crucial for mothers and their babies. To monitor the women at this stage, the partograph ...
Modelos alternativos da TRI para dados politômicos
(Universidade Federal de São Carlos, 2019-03-22)
The item response theory (IRT) models for polytomous data are frequently used in the analysis of data coming from the behavioral and social sciences. From a practical point of view, polytomous data are more informative ...
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 ...
Penalized regression methods for compositional data
(Universidade Federal de São Carlos, 2018-12-10)
Compositional data consist of known vectors such as compositions whose components are positive and defined in the interval (0,1) representing proportions or fractions of a "whole", where the sum of these components must ...
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 bayesianos zero-modificados para séries temporais de contagem
(Universidade Federal de São Carlos, 2020-04-30)
This work presents two Bayesian zero-modified (ZM) models for count time series: zero-modified Poisson ARMA and zero-modified COM-Poisson ARMA. The latter allows a greater flexibility since it has an aditional parameter ...
Diagnóstico de Influência Local para a obtenção de dados mascarados influentes em modelos de regressão com erros nas variáveis e propriedades assintóticas do modelo de calibração ultraestrutural
(Universidade Federal de São Carlos, 2020-05-08)
Proficiency testing determines the performance of individual laboratories with respect to specific measurement tests and it is used to monitor the reliability of laboratory measurements. Considering a multivariate measurement ...
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 ...
