In this paper, we first define a novel weighted correlation kernel (called wc-kernel) to measure the correlation of brain regions, by which weighting factors are learned in a data-driven manner to characterize the contributions of different time points, thus conveying the richer interaction ...
We develop a statistical theory to characterize correlations in weighted networks. We define the appropriate metrics quantifying correlations and show that strictly uncorrelated weighted networks do not exist due to the presence of structural constraints. We also introduce an algorithm for generating maxim...

Module significance is determined as the average absolute gene significance measure for all genes in a given module. When gene significance is defined as the correlation of gene expression profiles with an external trait y, this measure tends to be highly related to the correlation between the modu...

. Different approaches have been proposed in the literature to cope with this problem, but probably the most popular is the one related to distances/correlations (Kemeny and Snell1962; Cook et al.1986; Fagot1994; D’Ambrosio and Heiser2016). As a matter of fact, in order to obtain ...
R-squared value ranges from 0 to 1 and represents the strength of the correlations of the local model of the feature. The condition number is a measure of the stability of the estimated coefficients. Condition numbers above approximately 1000 indicate instability in the model; this i...
