Table 3. Type I error rates for bootstrap simulations.

Under 1,000 simulations with a binary outcome of accept or reject, deviations in type I error rates beyond a Wald confidence interval [0.036, 0.064] suggest deviations from a level 0.05 test not due to sampling. Scenarios where the error rates exceeded the Wald confidence bounds are bolded.
