Example for gp.cov.Coregion

I’m trying to understand gp.cov.Coregion - essentially, to reproduce this notebook from the Gpy docs in pymc3. I’ve googled extensively and can’t find an example usage. Does anyone have a gist or basic hello-world example for how it is intended to be used?

Absent that, my specific questions are:

  1. What are basic priors for W and kappa?
  2. How is the coregion kernel supposed to be used with another kernel - using Kronecker product?

Thanks,
Dan

I think @bwengals might have some examples using it?
