Pearson correlation full name
The most familiar measure of dependence between two quantities is the Pearson product-moment correlation coefficient (PPMCC), or "Pearson's correlation coefficient", commonly called simply "the correlation coefficient". It is obtained by taking the ratio of the covariance of the two variables in question of our numerical dataset, normalized to the square root of their variances. Mathe… WebUsing the Pearson correlation and three thresholds values (0.91; 0.92 and 0.93) the adjacency matrices and the associated networks were constructed as described in section 2.Then, the Louvain algorithm was used to detect the communities within each network. Essentially, Louvain is a two-step algorithm that maximises the modularity metric, in …
