'clr' infers an adjacency matrix using context likelihood/relatedness network using the 'clr' function from the 'parmigene' package. 'clr' will return the adjacency matrix containing the Context Likelihood of Relatedness Network-adjusted scores of Mutual Information values.
matrix, where columns and the rows are features (metabolites), cell entries are mutual information values between the features. As input, the mutual information (e.g. raw MI estimates or Jackknife bias corrected MI estimates) from the 'cmi' function of the 'mpmi' package can be used.
For more details on the 'clr' function, refer to '?parmigene::clr'. CLR computes the score sqrt(z_i ^2 + z_j ^2) for each pair of variables i, j, where z_i = max(0, ( I(X_i, X_j) - mean(X_i) ) / sd(X_i) ). mean(X_i) and sd(X_i) are the mean and standard deviation of the mutual information values I(X_i, X_k) for all k = 1, ..., n. For more information on the CLR algorithm see Faith et al. (2007).
