I've been using it on VMware Fusion for a couple years now. I can't remember exactly what I did, but this is just to note that it is definitely possible....

Very cool! I look forward to experimenting with this and trying to figure out what's going on soon.

I think there's an efficient TMB CAR model in here with a sparse matrix: https://github.com/mcruf/LGNB/blob/master/src/LGNB.cpp I think this part: https://github.com/mcruf/LGNB/blob/89d571731451e4ae05d94ae65f35bddf01630f11/src/LGNB.cpp#L118-L120 > The spatial covariance matrix Σ S , in contrast,...

Quickly: I believe this is a sum-to-zero constraint in TMB: https://github.com/mintoc/pnas_efm_paper/blob/ca66909e99d9552a4bad7116acdc3ca286e85963/dlm_ar1.cpp#L28-L30 although it beats me why this syntax works.

I tried simulation testing over 50 iterations here: https://github.com/pbs-assess/sdmTMB/blob/CAR/inst/sim-test-car.R ![image](https://user-images.githubusercontent.com/19349/149818902-f8359635-7ef3-415f-9d1c-ab5e81cf7727.png) The estimates look plausibly unbiased, although phi collapses to near zero in many cases even when set to 0.2.

I think that's related to this older issue: https://github.com/pbs-assess/sdmTMB/issues/54

Strangely, I can't reproduce the issue. (I did just push a fix for the annoying printing of the `sdmTMB_cv()` models where the data and mesh would be printed too.) ```...

This is done. Thanks @ericward-noaa. I'm not 100% sure if the Jacobian adjustment parts also need to be conditionally applied. If so, it isn't obvious to me how given they...

Some example code to work with: ```r # ... priors

Awesome, I just pushed some edits on the first half. Some quick answers: > Couple things I wanted to ask: > -I could use some help on using simulate() with...
