QQ plot of null LRT statistics with equal dispersion parameters. Data were simulated 100,000 times with μ=20 under the null hypothesis. Sample sizes were set at n=5,10,20,and 40. The LRT was used for testing mean difference between two conditions. The discrepancy of the null LRT statistics from chi-square distribution with 1 degree of freedom gets smaller when sample size increases
