Score Correlation
In this paper, we study a distribution-dependent correlation coefficient based on the concept of scalar score. This new measure of association of continuous random variables is compared by means of simulation experiments with the

Properties of the Weighted and Robust Implicitly Weighted Correlation Coefficients
Pearson product-moment correlation coefficient represents a fundamental measure of similarity between two data vectors. In various applications, it is meaningful to consider its weighted version known as the weighted Pe...

Correlation Power Analysis Distinguisher Based on the Correlation Trace Derivative
to extract the correct key guess is selecting the guess with the maximum Pearson correlation coefficient. We propose another distinguisher based on a significant change in the correlation trace rather than on the ...

Optimization of Pearson correlation coefficient calculation for DPA and comparison of different approaches
Differential power analysis (DPA) is one of the most common side channel attacks. To perform this attack we need to calculate a large amount of correlation coefficients. This amount is even higher when attacking FPGAs or ASICs, for ...

Testing equality of correlation coefficients in two populations via permutation methods
The present paper investigates the asymptotic behaviour of a studentized permutation test for testing equality of (Pearson) correlation coefficients in two populations. It is shown that this test is asymptotically of exact ...
