truncated_nbinom1 error in eigen(h)

[VetDoc23]

Hi there,

I am trying to fit a model to my data using:

glmmTMB(preMDS ~ 1 + relevel(as.factor(F_Absetzen), ref = "0") + (1 | Betrieb),
data = data,
family = "truncated_nbinom1")

But then I get this error:
"Error in eigen(h): infinite or missing values in 'x'
In addition: Warning messages:
1: In (function (start, objective, gradient = NULL, hessian = NULL, :
NA/NaN function evaluation
2: In (function (start, objective, gradient = NULL, hessian = NULL, :
NA/NaN function evaluation
[...]
8: In (function (start, objective, gradient = NULL, hessian = NULL, :
NA/NaN function evaluation
9: In (function (start, objective, gradient = NULL, hessian = NULL, :
NA/NaN function evaluation"

This occurs only with "F_Absetzen" and another factor from my data. With the other factors from my dataset I don't have any problems. I also tried other families (poisson, nbinom2, truncated_nbinom2) and they are working without any problem.

Do you know what could cause the problem? Could it still be my data, even if the other distributions are working?

I am happy about any suggestions!
Thank you!

Is there any chance you can send a reproducible example?

Thank you for your fast response! Yes, of course: This is a subset of my data and I still get the same error with the same two columns mentioned.

I'm still new to R and this topic in general. So I hope I didn't overlook anything obvious.
Pleas tell me, if you need further information.

I can see where this is running into trouble. I will see what I can do to fix it/get past this spot. In any case, it's not terribly surprising that this runs into trouble because it's a small noisy data set that might not match the specified model very well ...

Working on this here (should work OK, still fussing with side issues)

remotes::install_github("glmmTMB/glmmTMB/glmmTMB@try_jacobian")

and retry your example?
