WebFirst of all, there is a list of implemented priors available that can be used in the models straight away. These are described in Section 5.2. New priors can easily be implemented as well, as described in Section 5.3.

Fixing parameters to constants is possible by using the constant function, for example, constant(1) to fix a parameter to 1. Broadcasting to vectors and matrices is done automatically.
