    • Skeptical and Optimistic Robust Priors for Clinical Trials 

      Cook, John; Fúquene, Jairo; Pericchi Guerra, Luis Raúl
      A useful technique from the subjective Bayesian viewpoint, suggested by Spiegelhalter et al. (1994), is to ask the subject matter researchers and other parties involved, such as pharmaceutical companies and regulatory ...
    • The case for a fully robust hierarchical Bayesian statistical analysis of clinical trials 

      Pericchi Guerra, Luis Raúl; Pérez, María Eglée (International Workshop on Objective Bayes Methodology (OBayes 09),, 2009-06)
      Two clinical trials (past and present), conjugate priors are compared with (Robust) Cauchy- Student-t and what we call Berger's prior. The behavior of the latter Robust Bayesian methods is qualitatively di erent from ...
    • The Scaled Beta2 Distribution as a robust prior for scales, and a Explicit Horseshoe Prior for locations 

      Pérez, María Eglée; Pericchi Guerra, Luis Raúl
      In the tradition of ”Conjugate Priors” analysis (and extensions to Conditional Conjugate Priors), priors for locations are assumed Normal and for precisions are assumed Gamma or equivalently for variances Inverted Gamma. ...
    • Towards a General Theory of Optimal Testing 

      Pericchi Guerra, Luis Raúl; Pereira, Carlos
      In Pericchi and Pereira (2012)it is argued against the traditional way on which testing is based on xed signi cance level, either using p-values (with xed levels of evidence, like the 5% rule) or values. We instead, ...
