In statistics, the Pearson correlation coefficient rx,y determines the degree of linear correlation between two variables and it is known that −1 ≤ rx,y ≤ 1. In the theory of networks, a curious expression proposed in [PRL 89 208701 (2002)] for degree-degree correlation coefficient rji,ki , i ∈ [1,M ] has been in use. We realize that the suggested form is the conventional Pearson’s coefficient ...
This paper introduces a causation coefficient which is defined in terms of probabilistic causal models. This coefficient is suggested as the natural causal analogue of the Pearson correlation coefficient and permits comparing causation and correlation to each other in a simple, yet rigorous manner. Together, these coefficients provide a natural way to classify the possible correlation/causation...
Associations between two variables, for instance between brain and behavioral measurements, are often studied using correlations, and in particular Pearson correlation. However, Pearson correlation is not robust: outliers can introduce false correlations or mask existing ones. These problems are exacerbated in brain imaging by a widespread lack of control for multiple comparisons, and several i...
In this paper we present a method of abrupt cut detection with a novel logic of frames’ comparison. Actual frame is compared with its motion estimated prediction instead of comparison with successive frame. Four different similarity metrics were employed to estimate the resemblance of compared frames. Obtained results were evaluated by standard used measures of test accuracy and compared with e...
