Figure 4

Observed type I error rates of GLMM Wald F test with Satterthwaite approximation of denominator degrees of freedom. The type I error rates are calculated from 5000 independent simulation replicates. The solid grey lines indicate the nominal level and the dashed grey lines indicate the upper and lower bounds of the 95% confident interval.
