You may need to run it a couple of times before all the checks pass.

Thank you!

Thanks a lot @yahrMason.

I wonder if you already converted chapter 11?

[yahrMason]

@EAly

I have not gotten to chapter 11 yet, I am still working through chapter 10. I can take a look today though, I have picked up a few patterns of syntax that needs to be changed. Perhaps I can turn it around fairly quickly. I will let you know what I uncover.

Here is the PR for Chp 11 yahrMason:Chp11_v4

[EAly]

Awesome, thanks a lot!

@EAly
I updated the Chp11 code. I couldn't figure out the new arviz command for hpd (its hdi). I used a normal approximation to get around that and make the plots. I have made the change to hdi. I also made updates to 12 and 13.

Thanks a lot mate.
