I am new to Julia and i estimated some multilevel regressions using Mixed Models. Everything worked perfectly fine but i would like to estimate the marginal means or marginal effects. In R there are two packages that i am aware of for that regard: emmeans and ggeffects. Are there similar packages in Julia?
In Julia, there is now Effects.jl, which uses the same technique as the effects package in R (which is what ggeffects uses for its computation).
Since your question is tagged mixed-models, you might also consider JellyMe4 which adds support for lme4/MixedModels to RCall.
