glmmTMB support?

[pitakakariki]

Tricky bits probably:

• simulate with modified parameter values
• use.u in simulate

Hi, is there support for glmmTMB and powerSim() and powerCurve() at this point in time? Thanks!

[pitakakariki]

No support yet, but I've had another look and it might not be as hard as I thought. I'm unlikely to find the time for a while though.

[pitakakariki]

simulate.glmmTMB lives in methods.R.

object$obj$simulate(par = object$fit$parfull)$yobs

That goes back to TMB I think, but doSim should be able to pass modified parameters.

Hi @pitakakariki - wondering if you'd had chance to look at including this yet, or if you know of another method for glmmTMB?

[pitakakariki]

Not much progress on this unfortunately. Simplest way to do it might be to tweak your glmmTMB model by hand (i.e. edit the values in x$fit$parfull) and write functions to pass to fit and test.

[rosemckeon]

ok, thanks @pitakakariki - maybe I'll take a peek at that.

I'd be willing to help push this forward if you like. We really should add newparams and newdata to simulate.glmmTMB ...

[pitakakariki]

If newparams and newdata are added to simulate.glmmTMB that's most of the work done I reckon. That might finally encourage me to add the appropriate connectors at this end.

Actually, these are there already! There are some outstanding issues (https://github.com/glmmTMB/glmmTMB/issues/953) but you could give it a spin and see how it goes ...
