Final note on why genetic correlations are not squared.

چکیده

Correlations between related persons (twins, siblings, parent-child, etc.) should not be squared in order to determine the proportion of variance they have in common. The correlation coefficient itself is this proportion. We are not using the correlation to predict the variance in a given trait for one set of persons from a knowledge of the trait values of their relatives, but to express the degree of overlap in trait variance, that is, the proportion of variance in common. The rationale of genetic correlations is explained, with examples in terms of a common elements model of correlation.

Obtaining Squared Multiple Correlations from a Correlation Matrix Which May Be Singular*

A theorem is presented relating the squared multiple correlation of each measure in a battery with the other measures to the unique generalized inverse of the correlation matrix. This theorem is independent of the rank of the correlation matrix and may be utilized for singular correlation matrices. A coefficient is presented which indicates whether the squared multiple correlation is unity or n...

Aerodynamic Design Optimization Using Genetic Algorithm (RESEARCH NOTE)

An efficient formulation for the robust shape optimization of aerodynamic objects is introduced in this paper. The formulation has three essential features. First, an Euler solver based on a second-order Godunov scheme is used for the flow calculations. Second, a genetic algorithm with binary number encoding is implemented for the optimization procedure. The third ingredient of the procedure is...

Selecting effective features from Phonocardiography by Genetic Algorithm based on Pearson`s Coefficients Correlation

The heart is one of the most important organs in the body, which is responsible for pumping blood into the valvular systems. Beside, heart valve disorders are one of the leading causes of death in the world. These disorders are complications in the heart valves that cause the valves to deform or damage, and as a result, the sounds caused by their opening and closing compared to a healthy heart....

A Novel Intrusion Detection Systems based on Genetic Algorithms-suggested Features by the Means of Different Permutations of Labels’ Orders

Intrusion detection systems (IDS) by exploiting Machine learning techniques are able to diagnose attack traffics behaviors. Because of relatively large numbers of features in IDS standard benchmark dataset, like KDD CUP 99 and NSL_KDD, features selection methods play an important role. Optimization algorithms like Genetic algorithms (GA) are capable of finding near-optimum combination of the fe...
