Description A Bayesian statistical procedure consists of specifiying a priorprobability distribution for the unknown parameter, viewing the likelihood of the statistical model as giving the conditional distribution of the data given the parameter, and next updating the prior distribution to the conditional distribution of the parameter given the data, i.e. the posterior distribution.  In this course we shall be interested in the 'nonparametric' situation that the parameter is (possibly) a function, or another infinite-dimensional object. Then both prior and posterior are probabiity distributions on a function space. One example of a prior is the distribution of a stochastic process, for instance a Dirichlet or Gaussian process. We shall study examples of prior distributions (their definition, existence and some properties), and study the properties of the resulting posterior distributions.For the latter we adopt the 'frequentist framework', in which it is assumed that the data are generated according to a given parameter, and are usually concerned with the question whether the posterior is able to reconstruct this parameter, for instance if the amount of data would increase indefinitely.
