False positive error rate plot for both Wald test and LRT with equal dispersion parameters. False positive error rate was calculated for both Wald test (solid line) and LRT (dashed line) following a chi-square distribution with 1 degree of freedom at 5 different mean expression levels. The nominal false positive error rate for both Wald and LRT with the empirical distribution is shown in purple line (α=0.001). Both tests with the chi-square distribution have the inflated false positive error rates
