In this supplementary material, we provide the tables of empirical power values of the tests proposed in the main article. We have tabulated simulated powers of nonparametric bootstrap test N BTA, permutation test P M TA, two alternative tests N BTA1 and N BTA2 for FvML distribution by considering several combinations of sample sizes and concentration parameters. The robustness of these tests is also shown by implementing on contaminated FvML distributions.
