Fully crossed design
WebI'm trying to fit a GLMM on simulated response time data (continuous, positively skewed) obtained from hypothetical participants (Subject) responding to the same set of hypothetical items (Item), so it's a fully-crossed design. I intend to include several crossed-random effects for Subject and Item, so in lme4 language, it would look like the ... WebThe Crossed Multilevel Design. In one kind of 2-level model, there is not one random factor at Level 2, but two crossed factors. Each observation at Level 1 is nested in the combination of these two random factors. These …
