The normal approximation to the binomial test with and without a continuity correction is evaluated in terms of control of Type I errors and power. The normal approximations are evaluated as robust ...
An approximation of the exact distribution of the Wilcoxon test for symmetry by means of an Edgeworth series is derived. Probabilities are computed for sample sizes N = 10(1)26(2)42(3)48,50,100, and ...
