  • Changes in soil organic carbon under perennial crops 
    Ledo, Alicia; Smith, Pete; Zerihun, Ayalsew; Whitaker, Jeanette; Vicente‐Vicente, José Luis; Qin, Zhangcai; McNamara, Niall P.; Zinn, Yuri L.; Llorente, Mireia; Liebig, Mark; Kuhnert, Matthias; Dondini, Marta; Don, Axel; Diaz‐Pines, Eugenio; Datta, Ashim; Bakka, Haakon C.; Aguilera, Eduardo; Hillier, Jon (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    This study evaluates the dynamics of soil organic carbon (SOC) under perennial crops across the globe. It quantifies the effect of change from annual to perennial crops and the subsequent temporal changes in SOC stocks ...
  • 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 ...
  • Sensitivity and identification quantification by a relative latent model complexity perturbation in Bayesian meta-analysis 
    Roos, Malgorzata; Hunanyan, Sona; Bakka, Haakon C.; Rue, Håvard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    In recent years, Bayesianmeta-analysis expressed by a normal–normal hierarchical model (NNHM) has been widely used for combining evidence from multiple studies. Data provided for the NNHM are frequently based on a small ...
