Inferência bayesiana em modelos de volatilidade estocástica usando métodos de Monte Carlo Hamiltoniano
(Universidade Federal de São Carlos, 2018-08-10)
This paper presents a study using Bayesian approach in stochastic volatility models for modeling
financial time series, using Hamiltonian Monte Carlo methods (HMC). We propose the use
of other distributions for the errors ...
Detecting influential observations in spatial models using Bregman divergence
(Universidade Federal de São Carlos, 2018-02-26)
How to evaluate if a spatial model is well ajusted to a problem? How to know if it is the best model between the class of conditional autoregressive (CAR) and simultaneous autoregressive (SAR) models, including homoscedasticity ...
