WebI'm fitting a linear mixed-effects model with three fixed effects (and their interaction) and two random effects. I'm getting a significant main effect of one of the predictors, but if I remove this variable and fit a reduced model without it, the full model isn't preferred when I compare the models (p >.05, same AICs).
