It arises in the context of non-parametric tests that are based upon rankings. A "tie" is a case where two or more observations have the same value, and therefore share the same rank. A "non-zero tie" would be be a case where two or more observations share a non-zero value. Specifically, this comes up in the context of the Wilcoxon signed-rank test. This comment appears in gretl's nonparam.c: /* Wilcoxon signed-rank test, with handling of zero-differences and non-zero ties, plus continuity correction, as in E. Cureton, "The Normal Approximation to the Signed-Rank Sampling Distribution when Zero Differences are Present", JASA(62), 1967, 1068-1069. */ Frankly, I though this was too obscure to mark for translation, but the Czech translators noted the non-translated strings and requested that they be marked. Good luck! Allin. _______________________________________________ Gretl-devel mailing list Gretl-devel(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-devel
