Summary

In this paper we investigate the effect of estimating the center of symmetry on a Cramér-von Mises type statistic for testing the symmetry of a distribution function. The test statistic is defined by$$nT_0 \left[ {F_n } \right] = n\int_\infty ^\infty {\left\{ {F_n \left( x \right) + Fn\left( {2S\left[ {F_n } \right] - x} \right) - 1} \right\}^2 } dF_n \left( x \right),$$ whereFn is the empirical distribution function andS[Fn] is an estimator of the center ofF which is consistent with the ordern1/2 and has von Mises derivative. The asymptotic distribution ofnT0[Fn] under the null hypothesis is obtained. The distribution depends on the distributionF and on the estimatorS[Fn].
