A comparative study of Monte Carlo methods for efficient evaluation of marginal likelihoods
Ardia, David; Basturk, Nalan; Hoogerheide, Lennart; … - 2010
Strategic choices for efficient and accurate evaluation of marginal likelihoods by means of Monte Carlo simulation methods are studied for the case of highly non-elliptical posterior distributions. A comparative analysis is presented of possible advantages and limitations of different simulation...

Bayesian inference for the loss models via mixture priors
Deng, Min; Aminzadeh, Mostafa S. - In: Risks : open access journal 11 (2023) 9, pp. 1-27
Constructing an accurate model for insurance losses is a challenging task. Researchers have developed various methods to model insurance losses, such as composite models. Composite models combine two distributions: one for part of the data with small and high frequencies and the other for large...

An alternative conditional asymmetry specification for stock returns
Brännäs, Kurt; Nordman, Niklas - 2001
The paper advances the log-generalized gamma distribution as a suitable generator of conditional skewness. Based on the … NYSE composite daily returns an asMA-asQGARCH model along with skewness dynamics is estimated. The results indicate a … skewness that varies between sizeable negative skewness and almost symmetry. The conditional variance and skewness measures are …

Mixed normal conditional heteroskedasticity
Haas, Markus; Mittnik, Stefan; Paolella, Marc S. - 2002
Both unconditional mixed-normal distributions and GARCH models with fat-tailed conditional distributions have been employed for modeling financial return data. We consider a mixed-normal distribution coupled with a GARCH-type structure which allows for conditional variance in each of the...
