Bayesian Copula Directional Dependence is Cross-Network Robust for Gene-Regulatory Pair Direction: A Benchmark Study on DREAM5
Xiaoying Wei, Clara Grazian
Inferring the direction of a gene-regulatory relationship is harder than inferring whether a relationship exists, and most direction-inference methods are validated mainly on a sin…
Scalable Expectation Propagation for Mixed-Effects Regression
Jackson Zhou, John T. Ormerod, Clara Grazian
Mixed-effects regression models represent a useful subclass of regression models for grouped data; the introduction of random effects allows for the correlation between observation…
Stochastic Variational Inference for GARCH Models
Hanwen Xuan, Luca Maestrini, Feng Chen +1
Stochastic variational inference algorithms are derived for fitting various heteroskedastic time series models. We examine Gaussian, t, and skew-t response GARCH models and fit the…
An application of copulas to OPEC's changing influence on fossil fuel prices
Clara Grazian, Alex McInnes
This work examines how the dependence structures between energy futures asset prices differ in two periods identified before and after the 2008 global financial crisis. These two p…
Skew-Normal Posterior Approximations
Jackson Zhou, Clara Grazian, John Ormerod
Many approximate Bayesian inference methods assume a particular parametric form for approximating the posterior distribution. A multivariate Gaussian distribution provides a conven…
Bayesian Copula Directional Dependence for causal inference on gene expression data
Vasiliki Vamvaka, Clara Grazian
Modelling and understanding directional gene networks is a major challenge in biology as they play an important role in the architecture and function of genetic systems. Copula Dir…
New formulation of the Logistic-Gaussian process to analyze trajectory tracking data
Gianluca Mastrantonio, Clara Grazian, Sara Mancinelli +1
Improved communication systems, shrinking battery sizes and the price drop of tracking devices have led to an increasing availability of trajectory tracking data. These data are of…
