✦ Synopsis

Three approximations to the power function of the chi-square teat for the hypothema of 'no three factor interaction' in a 2 x2 x2 contingency table are introduced and compared. The firat method is baaed on the aampling distribution of the logarithm of the odds ratio, the second-on the noncentral distribution and the third-on the conditional distribution of a cell entry. The last method is found to provide the closest approximation under various alternative hypotheses and Bample sizes.
