Approximating Probability Levels for Testing Null Hypotheses with Noncentral F Distributions.
Fowler, Robert L.
Educational and Psychological Measurement, v44 n2 p275-81 Sum 1984
This study compared two approximations for normalizing noncentral F distributions: one based on the square root of the chi-square distribution (SRA), the other derived from a cube root of the chi-square distribution (CRA). The CRA was superior, and generally provided an excellent approximation for noncentral F. (Author/BW)
