WebNov 16, 2024 · With marginal means, we use our model to estimate means with predictors set to certain values. 2 For example, let’s say we’re interested in how the “black” race level changes the probability of developing diabetes for females at age 70. Previously, using marginal effects, we would set all 10,335 subjects to “black”, “female” and ...
WebDec 17, 2024 · Calculating confidence intervals of marginal means in linear mixed models. 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: WebOn this page we will use the lmer function which is found in the lme4 package. There are several other possible choices but we will go with lmer. The data were downloaded in Stata format from here and imported into R using the foreign library from a directory called …
