    • closedAccess   Geostatistical mixed beta regression: a Bayesian approach 

      Lagos Álvarez, Bernardo M.; Fustos Toribio, Roberto Miguel; Figueroa Zúñiga, Jorge; Mateu, Jorge Springer Verlag (2017)
      This paper develops regression techniques for geostatistical data, with an emphasis in proportions mea- sured on a continuous scale. Specifically, it deals with Beta regression models with mixed effects to control the ...

    • openAccess   Split Hamiltonian Monte Carlo revisited 

      Casas, Fernando; Sanz-Serna, JM; Shaw, Luke Daniel Springer (2022)
      We study Hamiltonian Monte Carlo (HMC) samplers based on splitting the Hamiltonian H as H0(θ , p)+U1(θ ), where H0 is quadratic and U1 small. We show that, in general, such samplers suffer from stepsize stability restrictions ...
