hierarchical variances #56

Open psycharo-zz opened 11 years ago

currently, only constant parents for both gamma and Wishart distributions are supported. This does not allow hierarchical variance modelig e.g. like in http://arxiv.org/abs/1207.1380 It is possible to tackle this problem by sampling methods/non-conjugate models
