Modelos COM-Poisson correlacionados
(Universidade Federal de São Carlos, 2019-04-23)
In this thesis two discrete distributions are proposed: Correlated COM-Poisson (CPC) and
Generalized partially correlated COM-Poisson (CPGPC). We have also proposed regression
models for the Generalized partially correlated ...
Seleção de modelos multiníveis para dados de avaliação educacional
(Universidade Federal de São Carlos, 2017-08-11)
When a dataset contains a hierarchical data structure, a possible approach is the multilevel
regression modelling, which is justified by the significative amout of the data variability that can
be explained by macro level ...

Cancer is responsible for about 13% of all deaths in the world occuring mainly in people who
are late diagnosed and in advanced stages. Due to its devastating characteristics and the growing
prevalence of the disease, ...
Quantificação em problemas com mudança de domínio
(Universidade Federal de São Carlos, 2018-05-17)
Several machine learning applications use classifiers as a way of quantifying the prevalence of positive class labels in a target dataset, a task named quantification. For instance, a naive way of determining what proportion ...
Modelos preditivos para LGD
(Universidade Federal de São Carlos, 2018-05-04)
Financial institutions willing to use the advanced Internal Ratings Based (IRB) need to develop
methods to estimate the LGD (Loss Given Default) risk component. Proposals for PD (Probability
of default) modeling have ...

(Universidade Federal de São Carlos, 2019-04-12)
Areas such as politics, economics and marketing are heavily influential in terms of information diffusion. For this reason, several branches of science have studied such phenomena in order to simulate and understand them ...
Contribuições sobre o envelope simulado na análise de diagnóstico em modelos de regressão
(Universidade Federal de São Carlos, 2019-04-30)
The simulated envelope is a diagnostic analysis method used to evaluate the hypothesis about the probability distribution assumed for the response variable in a regression model. In this work, we describe some procedures ...
Abordagem de martingais para análise assintótica do passeio aleatório do elefante
(Universidade Federal de São Carlos, 2018-08-20)
In this work we study the elephant random walk introduced in (SCHUTZ; TRIMPER, 2004),
a discrete time, non-Markovian stochastic process with unlimited range memory that presents
phase transition. Our objective is to proof ...
Modelagem da volatilidade em séries temporais financeiras via modelos GARCH com abordagem bayesiana
(Universidade Federal de São Carlos, 2017-07-18)
In the last decades volatility has become a very important concept in the financial area, being used
to measure the risk of financial instruments. In this work, the focus of study is the modeling of
volatility, that ...
