Comparing the reliability of a discrete-time and a continuous-time Markov chain model in
discrete-time transition matrix the default probability the empirical results
2011/8/30
This article compares the reliability of a discrete-time and a continuous-time Markov chain model for estimating credit risk and for investigating loans of Chiao Tung Bank in Taiwan. The continuous-ti...
Geometric Allocation Approach for Transition Kernel of Markov Chain
Markov chain Transition kernel Geometric allocation Detailed balance Reversibility
2011/7/5
We introduce a new geometric approach that constructs a
transition kernel of Markov chain. Our method always minimizes the av-
erage rejection rate and even reduce it to zero in many relevant cases,...
Model Selection and Adaptive Markov chain Monte Carlo for Bayesian Cointegrated VAR model
Cointegrated Vector Auto Regressions Markov chain Monte Carlo
2010/4/28
This paper develops a matrix-variate adaptive Markov chain Monte Carlo (MCMC) methodology for Bayesian Cointegrated Vector Auto Regressions (CVAR). We replace the popular approach to sampling Bayesian...
A Coupled Markov Chain approach to risk analysis of credit default swap index products
Coupled Markov Chain risk analysis credit default swap index products
2010/11/3
We apply a Coupled Markov Chain approach to model rating transitions and thereby default probabilities of companies. We estimate parameters by applying a maximum likeli-hood estimation using a large 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
construction ...
An Adaptive Markov Chain Monte Carlo Method for GARCH Model
Chain Monte Carlo Bayesian inference GARCH model Metropolis-Hastings algorithm
2010/10/29
We propose a method to construct a proposal density for the Metropolis-Hastings algorithm in Markov Chain Monte Carlo (MCMC)simulations of the GARCH model. The proposal density is constructed adaptive...
