Abstract
The empirical likelihood ratio (ELR) test for the problem of testing for normality is derived in this article. The sampling properties of the ELR test and four other commonly used tests are provided and analyzed using the Monte Carlo simulation technique. The power comparisons against a wide range of alternative distributions show that the ELR test is the most powerful of these tests in certain situations.

Notes
Notes: m and n are the number of replications and the sample size. The true values of the parameters (μ, σ2)′ = (0, 1)′. The χ2 tests may not be applicable with some small sample sizes.
Notes: The number of replications is 10,000. n is the sample size. The true values of the parameters (μ, σ2)′ = (0, 1)′. The χ2 tests may not be applicable with some small sample sizes.

Notes: The number of replications is 10,000. n is the sample size. The data is standardized to be x i = (y i − μ)/σ, for i = 1, 2,…, n. The true values of the parameters (μ, σ2)′ = (0, 1)′.
Notes: The number of replications is 10,000. n is the sample size. The true values of the parameters (μ, σ2)′ = (0, 1)′. ELR4 and ELR5 are the ELR test with four and five moment equations, respectively. The degrees of freedom of the ELR5 test is 3. The alternative of student t (5) is not applicable in this excise.
