摘要：
Explicit expressions for the exact cumulants of Fisher''s z-distribution are given. Cumulants for the logarithmic x 2-distribution are first found (the same result was published by Bartlett and Kendall in 1946) and the cumulants of 2 obtained by considering the z-distribution as the difference between two logarithmic x 2-distributions. Cumulants of the logarithmic t-distribution are obtained by specializing the z-distribution.
