In my PyMC model there exists a conditional statement within the model. I wish to have the sampler consider the value of a deterministic variable to be valid only when this condition is true. I believe it used to possible to return i.e. -np.inf for a draw to be rejected, but this seems to cause som…

This may be helpful: pymc.model.core.Potential — PyMC dev documentation However it’s better to avoid hard constraints when sampling with NUTS, since it requires some degree of continuity. It’s usually possible to write constrains in a more soft continuous way or by being clever about variable prior…

This works. Thanks a lot!
