Bayesian Linear Mixed Models - categorical fixed effect with more than two levels

Hi,

I have a question regarding Bayesian mixed effect models. I actually use R to run the models, but I ran into an issue with one of my models and tried to run the same in JASP. In this model, one of my fixed effects has 6 levels. I receive estimates for 5 of the levels compared to the reference level, but first I would like to know whether the fixed effect has a general main effect (i.e., not per level). So far, I could only figure out how to get results for main and interaction effects via ANOVA summary, which is also automatically shown in JASP when I run the frequentist analysis. When I then run the Bayesian analysis, I again only get estimates for the separate levels. Is there any way to get the results in the ANOVA summary table also for Bayesian analyses?

Thanks in advance,

Faya
