Welcome to Wikiprevia, a collaborative project on objective Bayesian methods
What is Wikiprevia about
An essential piece of every Bayesian analysis is the prior distribution of the unknown parameters. In many circumstances users of Bayesian methods do not have the resources to assign prior distributions based on expert knowledge. Others simply do not want to include any extra information in the analysis other than the model specified and the data. In these circumstances the use of an `objective’ prior is called for and the natural question of which prior should be used arise.
Wikiprevia is a collaborative project that is aimed at collecting and giving access to all relevant information about specific formal objective priors for particular problems with the tutelage of the Objective Bayesian section of ISBA.
In Wikiprevia, the perspective under which the problem of objective priors is approached is explained in . Wikiprevia can be considered a modern version of the Catalogue of non-informative priors .
In Spanish the `previa' means `prior' and if you mix Wiki+previa a word that sounds like Wikipedia shows up.
Recommended priors are organized in the following categories:
