Marginaleffects - obtaining contrasts and plotting predictions

Using marginaleffects, I was trying to

  1. obtain contrasts by "period"
  2. visualize the predictions by "period"
  3. visualize the predictions by "session"

And failed in all! Any help is appreciated.

import dat_long
dat_long$group <- as.factor(dat_long$group)
dat_long$period <- as.factor(dat_long$period)


dat_long <- dat_long %>% 
  mutate(group2 = group)


m222 <- lmer(money ~ session + period + group2 + (1 | id2) + (1 | session / date / period), data = dat_long ) 
summary(m222)

  m222,
  variables = "period",
  include_random = FALSE,
  newdata = datagrid(
    period = c("p1", "p2", "p3", "p4")

Solution

  • This answer uses the development version (0.9.0.9043) of marginaleffects, which you can install by following the instructions here: https://vincentarelbundock.github.io/marginaleffects/

    Please note that the extra lme4-related arguments must be supplied to the predictions() function, and not to the datagrid() function as you do in your second example.

    Also, I strongly suggest you avoid include_random and use the default arguments supplied by the lme4 modelling package itself (via predict.merMod). In this case: re.form and allow.new.levels.

    library(lme4)
library(lmerTest)
library(marginaleffects)
library(dplyr)

dat_long$group <- as.factor(dat_long$group)
dat_long$period <- as.factor(dat_long$period)
dat_long <- dat_long %>% mutate(group2 = group)

m222 <- lmer(money ~ session + period + group2 + (1 | id2) + (1 | session / date / period), data = dat_long ) 

comparisons(
    m222,
    variables = "period",
    re.form = NA,
    newdata = datagrid(period = c("p1", "p2", "p3", "p4")))
