Adaptive estimation of the copula correlation matrix for semiparametric elliptical copulas

We study the adaptive estimation of copula correlation matrix Σ for the semi-parametric elliptical copula model. In this context, the correlations are connected to Kendall's tau through a sine ...

Beyond the Gaussian copula: stochastic and local correlation

We consider stochastic correlation models that account for the correlation smile in the pricing of synthetic CDO tranches. These can be viewed as tractable extensions of the one-factor Gaussian copula ...

Modeling overnight and daytime returns using a multivariate generalized autoregressive conditional heteroskedasticity copula model

We introduce a multivariate generalized autoregressive conditional heteroskedasticity (GARCH) copula model to describe joint dynamics of overnight and daytime returns for multiple assets. The ...

A time-varying Bayesian joint hierarchical copula model for analysing recurrent events and a terminal event

Recurrent events could be stopped by a terminal event, which commonly occurs in biomedical and clinical studies. Taking the Cardiovascular Health Study as a motivating example, patients can experience ...
