WebPearson r correlation: Pearson r correlation is the most widely used correlation statistic to measure the degree of the relationship between linearly related variables. For example, in the stock market, if we want to measure how two stocks are related to each other, Pearson r correlation is used to measure the degree of relationship between the two. The point … 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 …
