    We propose the approximate Laplace approximation (ALA) to evaluate integrated likelihoods, a bottleneck in Bayesian model selection. The Laplace approximation (LA) is a popular tool that speeds up such computation and ...
  • Rossell Ribera, David (International Society for Bayesian Analysis, 2022)
    We study frequentist properties of Bayesian and L0 model selection, with a focus on (potentially non-linear) high-dimensional regression. We propose a construction to study how posterior probabilities and normalized L0 ...
  • Rossell Ribera, David; Zwiernik, Piotr (Institute of Mathematical StatisticsBernoulli Society for Mathematical Statistics and Probabilit, 2021)
    The Gaussian model equips strong properties that facilitate studying and interpreting graphical models. Specifically it reduces conditional independence and the study of positive association to determining partial correlations ...
  • Jewson, Jack; Rossell Ribera, David (Oxford University Press, 2022)
    Statisticians often face the choice between using probability models or a paradigm defined by minimising a loss function. Both approaches are useful and, if the loss can be re-cast into a proper probability model, there ...
  • Avalos-Pacheco, Alejandra; Rossell Ribera, David; Savage, Richard S. (International Society for Bayesian Analysis, 2022)
    Two key challenges in modern statistical applications are the large amount of information recorded per individual, and that such data are often not collected all at once but in batches. These batch effects can be complex, ...
  • Palacio Lozano, Diana Catalina; Jones, Hugh E.; Gavard, Remy; Thomas, Mary J.; Ramírez, Claudia X.; Wootton, Christopher A.; Sarmiento Chaparro, José Aristóbulo; O’Connor, Peter B.; Spencer, Simon E. F.; Rossell Ribera, David; Mejía-Ospino, Enrique; Witt, Matthias; Barrow, Mark P. (American Chemical Society (ACS), 2022)
    Bio-oils are precursors for biofuels but are highly corrosive necessitating further upgrading. Furthermore, bio-oil samples are highly complex and represent a broad range of chemistries. They are complex mixtures not simply ...
  • Gavard, Remy; Guzman, Alexander; Rossell Ribera, David; Spencer, Simon E. F.; Barrow, Mark P. (American Chemical Society (ACS), 2019)
    Fourier transform ion cyclotron resonance mass spectrometry (FTICR MS) provides the resolution and mass accuracy needed to analyze complex mixtures such as crude oil. When mixtures contain many different components, a ...
  • Semken, Christoph; Rossell Ribera, David (Oxford University Press, 2022)
    A key issue in science is assessing robustness to data analysis choices, while avoiding selective reporting and providing valid inference. Specification Curve Analysis is a tool intended to prevent selective reporting. ...
