Marginal effects in r
WebJan 7, 2024 · Take the average of the unit-level slopes (average marginal effect) In models like nnet::multinom, the slopes will be different for every level of the outcome variable. There will thus be one average marginal effect per level, per regressor.

It seeks to model a population average. Mixed-effect/Multilevel models are subject-specific, or conditional, models. They allow us to estimate different parameters for each subject or cluster. In other words, the parameter estimates are conditional on the subject/cluster.
