6 years ago Marianne,
many thanks for the careful reading - approved and merged your changes. are you using this model or planning on using it?
my talk at the Ann Arbor R Users group went OK. it was a learning experience all around, and I've got a long way to go w/r/t case study, talk, and further work.
cheers, Mitzi
Hi @mitzimorris!
Hope this finds you well.
I'm not entirely sure of my changes, which is why I checked "Allow edits from maintainers."
I understand that there are $n$ regions and we identify a region by $i$ (and, say, another region by $j$). So $i$ runs from $1, ..., n$.
But, apparently, there are also "$n$ different areal units of a region" (in a region? in each region?); then I would understand $n_i$ to be an areal unit of region $i$.
Does $n_i = 1, ..., n$? It would seem odd that this would be the same $n$ (number of regions vs. number of areal units per region).
Am I completely off? Please let me know!
I've also noticed that, starting at section "Adding an ICAR component to a Stan model," $n$ (which one?) seems to become $N$ while, earlier on, $N$ is used to denote the normal distribution.
