Um novo estimador exponencial por partes da curva de sobrevivência: um estudo comparativo
(Universidade Federal de São Carlos, 2006-05-31)
In this work we revise the main basic concepts on survival analysis and reliability.
We present the most known nonparametric estimators of the survival function in the
presence of censured data. Their estimates are ...
Uma proposta para análise de dados com correlação espacial e temporal
(Universidade Federal de São Carlos, 2007-09-27)
In several research areas, the study of the occurrence of a phenomenon over a
period of time is very common. In this case, if we use the theory of Generalized Linear
Models to analyze the subject of interest, we ll have, ...
Uso de métodos bayesianos em testes de vida acelerados no controle da qualidade de produtos industriais
(Universidade Federal de São Carlos, 2006-03-03)
In this work, we introduce a Bayesian approach for quality control of industrial products, assuming units in test under stress levels higher than the usual level. We assume di¤erent distributions for the lifetimes of the ...

Modelagem estatística para a determinação de resultados de dados esportivos
(Universidade Federal de São Carlos, 2007-06-27)
The basic result of a soccer game is the final scoreboard, which can be seen as a
bivariate random vector. Theoretically and based on existent literature we can argue that
the number of marked gols by a team in a game ...

In the medical area, diagnostic tests are used to classify a patient as positive or
negative with respect to a given disease. There are simple and more elaborate tests, each

Estimativas de máxima verosimilhança e bayesianas do número de erros de um software
(Universidade Federal de São Carlos, 2006-02-24)
In this work we present the methodology of capture-recapture, under the classic and bayesian approach, to estimate the number of errors of software through inspection
by distinct reviewers. We present the general statistical ...
Um enfoque bayesiano do modelo de captura-recaptura na presença de covariáveis
(Universidade Federal de São Carlos, 2006-02-22)
This work has as main objective to insert covariates in the capture probability of the multiple capture-recapture method for closed animal population. Factors like climate, seasons of the year, animal size, could a¤ect the ...
