GAMLj Mixed Model output (dots being displayed)

[dansquared]

Hi all,

I'm running a mixed model and the output of some interactions are not showing although the model seemed to converge.
Dots (.) end up being displayed in the estimate, SE, df, t and p sections.

Why is that?

Really appreciate your help!

Hi
dots are usually displayed when the estimation did not found a reasonable solution, which is another way to say that there was an issue with convergence. In other cases, some fixed effects cannot be estimated because of lack of degrees of freedom, or perfect collinearity. That said, if you share an example it would be easier to understand what is going on
