MacCallum, Browne, and Sugawara (1996) published an article on power analysis and determination of minimum sample size for tests of model fit in covariance structure analysis. In an appendix of that article are two SAS programs. The first program estimates power of a model test, and the second program estimates minimum sample size required to achieve a given level of power.
