Apologies if this is a silly question but I am a student
and this is my first time using R so I am still trying to
educate myself on commands, models e.t.c
I have a mixed model with four dichotomous fixed factors and
subject as a random factor (as each person
completed four vignettes, with factors crossed across vignettes).
I have run an lmer model and used the Monte Carlo method to
see if there are any significant main effects or
interactions. However, when I looked at the p values
some are showing as significant although the F value
is less than 1. Is it possible to have a significant
effect with an F value below 1?.
I have a sample size of 150 and have read that the
pMCMC values can be anti-conservative so wonder if it is
because my sample size may be too small?.
