  • APPROXIMATE BAYESIAN INFERENCE FOR ANALYSIS OF SPATIOTEMPORAL FLOOD FREQUENCY DATA 
    Jóhannesson, Árni V.; Siegert, Stefan; Huser, Raphaël; Bakka, Haakon; Hrafnkelsson, Birgir (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Extreme floods cause casualties and widespread damage to property and vital civil infrastructure. Predictions of extreme floods, within gauged and ungauged catchments, is crucial to mitigate these disasters. In this paper ...
  • Max-and-Smooth: A Two-Step Approach for Approximate Bayesian Inference in Latent Gaussian Models 
    Hrafnkelsson, Birgir; Siegert, Stefan; Huser, Raphaël; Bakka, Haakon C.; Jóhannesson, Árni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    With modern high-dimensional data, complex statistical models are necessary, requiring computationally feasible inference schemes. We introduce Max-and-Smooth, an approximate Bayesian inference scheme for a flexible class ...
