I wrote a 2-part blog post about custom likelihood functions using DensityDist in PyMC3. I’m drawing from real examples I had to work on as I learned how to use DensityDist. I thought some beginning users might be interested.

Hi – I would like to have access the blog, but the links don’t seem to work.  
Any chance the blog can be made accessible somewhere?  
Thank you!
