The short url listed there doesn't lead to pymc documentation, instead leads to the linked in page of "Melanya Kirakosyan".

Thanks for reporting. That's kind of funny no idea who she is. The link should point to https://www.pymc.io/projects/docs/en/stable/learn/core_notebooks/pymc_overview.html#case-study-2-coal-mining-disasters
