Abstract
This article studies the effect of estimating the center of symmetry by the sample mean on the sign test for symmetry. Under the null hypothesis, the modified sign test is not distribution-free. Indeed, the asymptotic variance of the modified sign test can be quite different from that of the standard sign test.Keywords
