A new class of discrete models for the analysis of zero-modified count data
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2020-04-03)
In this work, a new class of discrete models for the analysis of zero-modified count data has been introduced. The proposed class is composed of hurdle versions of the Poisson-Lindley, Poisson-Shanker, and Poisson-Sujatha ...
Degradation modeling for reliability analysis with time-dependent structure based on the inverse gaussian distribution
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2017-04-07)
Conventional reliability analysis techniques are focused on the occurrence of failures over
time. However, in certain situations where the occurrence of failures is tiny or almost null, the
estimation of the quantities ...
Modelagem de fraude em cartão de crédito
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2008-09-02)
The transactions volume increase brought the fraud increase, which result in a annual loss of billions of reais to all .nancial institutions in the world. Therefore, it.s very important the development of detection methods ...
Um estudo de estresse através dos níveis de cortisol em crianças
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2017-05-26)
The level of cortisol is considered as a measure of people’s stress. We perform an
statistical analysis of the data from a study conducted to evaluate if children that
work on the streets during the day have higher stress ...
Uma adaptação da teoria de homologia para problemas de reconhecimento topológico de padrões
(Universidade Estadual Paulista (Unesp), 2018-03-09)
O objetivo dessa dissertação é apresentar parte do artigo [2] de Gunnar Carlsson, onde se discute a adaptação de métodos da teoria usual de homologia para problemas de reconhecimento topológico de padrões em conjuntos de ...
Data fusion of laser-induced breakdown spectroscopy and spectral reflectance techniques for estimating the mineralogical composition of copper concentrates.
(Universidad de Concepción, Facultad de Ingeniería, Departamento Ingeniería Eléctrica., 2021)
The pyrometallurgical copper industry faces some challenges in terms of the instrumenta tion for its processes. In this work, Laser-Induced Breakdown Spectroscopy (LIBS) data will
be studied and combined with Diffuse ...
Criação de um ambiente computacional para detecção de outliers e preenchimento de falhas em dados meteorológicos
(Universidade Federal de Mato GrossoBrasilInstituto de Física (IF)UFMT CUC - CuiabáPrograma de Pós-Graduação em Física Ambiental, 2015-02-27)
In order to study the environment meteorological data series must be
analyzed. However, these data series may contain errors, because of electronic
failures, animal action or weather phenomena, among other factors. These ...
