I'm using different R packages ( effects, ggeffects, emmeans, lmer) to calculate confidence intervals of marginal means in a linear mixed model. My problem is that the effects package produces smaller CIs compared to other methods. Here is an example:. This table displays the model-estimated marginal means and standard errors of Amount spent at the factor combinations of Gender and Shopping style.This table is useful for exploring the possible interaction effect between these two factors.
