O efeito de reparametrização em testes de sobrevivência acelerados
(Universidade Federal de São Carlos, 2003-06-11)
Accelerated life tests are frequently used in industrial experiments to obtain measures on the reliability of products. In these tests, the units are submited at higher levels of stress than usual and the informations ...
Especificação do tamanho da defasagem de um modelo dinâmico
(Universidade Federal de São Carlos, 2009-03-06)
Several techniques are proposed to determine the lag length of a dynamic regression model. However, none of them is completely satisfactory and a wrong choice could imply serious problems in the estimation of the parameters. ...
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 ...
Modelo de regressão com erros normais assimétricos: uma abordagem bayesiana
(Universidade Federal de São Carlos, 2005-12-13)
The statistical analysis of the continuous data set has been developed in most cases for normal models, specially, in the linear and nom linear models context. In the simple linear regression models, even accepting as ...
