Some nonparametric tests of symmetry based on the sample entropy of order statistics are presented. Our tests have this advantage that we do not need to estimate the center of the symmetry. Monte Carlo studies show that, for a wide variety of alternative asymmetric distributions, the proposed tests are much more powerful than previously proposed tests. A real example is used to illustrate the proposed procedures. Keywords and phrases Test of symmetry Entropy Power of test Generalized lambda family
