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 ...
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 ...
Metodologia gráfica para dados de eventos recorrentes via bootstrap.
(Universidade Federal de São Carlos, 2005-01-05)
Experiments related to recurrent events provide information about the number of events,
time to their ocurrence and their costs. Nelson (1995) presents a methodology to obtain
confidence intervals for the cost and the ...
Classe de distribuições série de potências inflacionadas com aplicações
(Universidade Federal de São Carlos, 2009-04-06)
This work has as central theme the Inflated Modified Power Series Distributions, where the objective is to study its main properties and the applicability in the bayesian context. This class of models includes the generalized ...
Reamostragem bootstrap em amostragem por conjuntos ordenados e intervalos de confiança não paramétricos para a média.
(Universidade Federal de São Carlos, 2005-01-27)
Ranked set sampling is an efficient and practice way to obtain more precise estimative
when the sample size is small because of the high cost or difficulties to measure the interest
variable. Using rough and cheap qualitative ...
Intervalos de confiança para dados com presença de eventos recorrentes e censuras.
(Universidade Federal de São Carlos, 2003-05-23)
In survival analysis and reliability is common that the population units in study presents
recurrence events and censoring ages, besides, is possible to exist a cost related to each event
that happens. The objectives of ...
Métodos estatísticos aplicados à análise da expressão gênica
(Universidade Federal de São Carlos, 2006-02-23)
The technology of the DNA-Arrays is a tool used to identify and to compare levels of expression of a great number of genes or fragments of genes, in di¤erent conditions.
With this comparison, it is possible to identify ...
Uso do processo gama para dados de sobrevivência.
(Universidade Federal de São Carlos, 2005-01-20)
In this dissertation, we introduce classical and Bayesian approaches to get inferences
on the parameters of interest, considering exponential and Weibull distributions for the
lifetimes. For a Bayesian analysis, we assume ...
Distribuição normal assimétrica para dados de expressão gênica
(Universidade Federal de São Carlos, 2009-04-17)
Microarrays technologies are used to measure the expression levels of a large amount of genes or fragments of genes simultaneously in diferent situations. This technology is useful to determine genes that are responsible ...
