I have this mode starting model but I need to build the random structure but I am not sure if I can do that without setting the contrasts. Variable
Time is a 3-level factor and I want to run pairwise comparisons but that is not an option for the standard contrasts, so I will run emmeans (after building the model). Will that influence the results? I usually set the contrasts before building the model.
model <- lmer(RT ~ Block * Type * Time + (1 | Participant), data = Data.trimmed, REML = FALSE)
