We propose the use of projection correlation to characterize dependence between two random vectors. Projection correlation has several appealing properties. It equals zero if and only if the two random vectors are independent, it is not sensitive to the dimensions of the two random vectors, it is invariant with respect to the …

The naming of the coefficient is … See more The values of both the sample and population Pearson correlation coefficients are on or between −1 and 1. Correlations equal to +1 or −1 … See more Statistical inference based on Pearson's correlation coefficient often focuses on one of the following two aims: • One … See more The square of the sample correlation coefficient is typically denoted r and is a special case of the coefficient of determination. In this case, it estimates the fraction of the variance in Y that is explained by X in a simple linear regression. … See more Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations.
