2011/7/25
Abstract: Recent work of Dupire (2005) and Carr & Lee (2010) has highlighted the importance of understanding the Skorokhod embedding originally proposed by Root (1969) for the model-independent hedgin...
Bayesian Inference on QGARCH Model Using the Adaptive Construction Scheme
Bayesian Adaptive Construction Scheme
2010/11/1
We study the performance of the adaptive construction scheme for a Bayesian inference on the Quadratic GARCH model which introduces the asymmetry in time series dynamics.In the adaptive construction s...
Markov Chain Monte Carlo on Asymmetric GARCH Model Using the Adaptive Construction Scheme
Markov Chain Monte Carlo Bayesian inference
2010/11/2
We perform Markov chain Monte Carlo simulations for a Bayesian inference of the GJR-GARCH model which is one of asymmetric GARCH models. The adaptive construction scheme is used for the
