13. Modelos de regressão logística clássica, Bayesiana e redes neurais para Credit Scoring
Important advances have been achieved in the granting of credit, however, the problem of identifying good customers for the granting of credit does not provide a definitive solution. Several techniques were presented and are being developed, each presents its characteristics, advantages and disadvantages as to their discrimination power, robustness, ease of

14. Bayesian inference in a quantitative genetic study of growth traits in Nelore cattle (Bos indicus)
The objective of this study was to estimate (co)variance components and genetic parameters for weights (W) and scrotal circumferences (SC) at 365 and 450 days of age, of Nelore (Bos indicus) cattle, using Bayesian inference in single and multiple-trait animal models. The fitted linear models included, besides the animal and residual random effects, the conte

15. Variabilidade genética em caprinos
They were appraised 187 animals of Moxotó breed raised on Paraíba, Pernambuco and Mossoró-RN State, and 46 Serpentina goats in Portugal with the objective of verify the genetic relationship among Moxotó herds and those ones with the Serpentina breed. 25 microsatellit was used and, all were shown polimorphyc and good equilibrium levels once 60% of the mar

16. Um modelo integrado de inferÃncia Bayesiana e processos Markovianos para anÃlise de sistemas reparÃveis sujeitos a reparo imperfeito via processo de renovaÃÃo generalizado
This dissertation deals with repairable systems submitted to imperfect repair, using a class of stochastic models known as Generalized Renewal Process (GRP), which allows to insert flexibility to approach diverse levels of repair. For such objective, is proposed an non-homogeneous Markovian process model to analyze the dynamic behavior of complex systems, us

17. BAYESIAN INFERENCE ON MULTIVARIATE ARCH MODELS / MODELAGEM BAYESIANA MCMC PARA UM PROCESSO ARCH MULTIVARIADO / MODELOS BAYESIANOS MCMC PARA UN PROCESO ARCH MULTIVARIADO
The objective of this work is to develop Metropolis-Hasting for strategy Bayesian Inference, based on a Multivariate ARCH model with BEKK representation. In complex problems, such as the multivariate generalization of ARCH/GARCH structures, the inference process in complicated, due to the large number of parameters involved and to the restrictions they must
