Pearson Product-Moment Correlation

The Rank Correlation Coefficient as an Indicator of the Product-Moment Correlation Coefficient for Small Samples

On the basis of 2200 small (10-100) samples obtained from four random number populations, it is shown that the rank correlation coefficient, p, is 88 adequate a measure of concordance 88 the Pearson product-moment correlation, T. The samples were obtained by using pseudo-random linear and normal number generators for bivariate populations with expected correlation cC'efficientB, r~, of 0.0 and ...

Quadrupole moment function and absolute infrared quadrupolar intensities for N2.

High level ab initio methods have been used to calculate values of the quadrupole moment of the ground X (1)Sigmag+ state of N2 on a dense radial mesh spanning the interval of 0.8-12.1 a.u. Detailed convergence tests indicate that the resulting equilibrium values of the quadrupole moment Theta(e)=-1.1273 a.u. and its first radial derivative dTheta(R)/dR/e=0.9604 a.u. have absolute uncertainties...

Calculation of Linkage Intensities Where Duplicate Factors Are Concerned.

For the calculation of linkage intensities, i t is of distinct advantage to back-cross the heterozygote on the double recessive since the gametic ratio can then be determined directly from the zygotic types. In some plants, as corn, for example, back-crosses are easily and readily made, but in others, as soy-beans, the practical difficulties attending artificial hybridization are too great to a...
