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 ...
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 ...
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 ...
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 ...
