摘要：In entomological field experiments the variance of the number of insects per plot may be a quadratic function of the mean number of insects, i.e.: o2 = M + kM 2. In such cases the transformation x'' = k-1/3 sinh-1 (kx)1/2, where x is the number of insects, tends to bring the variances closer to equality and enables the analysis of variance to be applied to the transformed data. To facilitate the use of this transformation, a table of x'' is given to 2 decimal places for x = 0(1)50(5)100(10)300...

摘要：The first 4 moments are calculated lor any power of a normally-distributed variate and for the product of any number of normally-distributed variates (whether correlated or uncorrelated). Results are expressed in terms of the means and coeffs. of variation of the original distributions. Since linear measurements on biol. material are frequently nearly normal in their distributions, these results may be applicable to the distributions of the wts. or volumes of organisms.
