principal path from the starting point to the ending point |
A list of objects
correlations: Pearson's correlation coefficients between ea ch feature and the path (when ppath_perturbed is not NULL, a Fisher-integrated correlation coefficient is provided)
ranks: ranks of associations between the n features and the path (when ppath_perturbed is not NULL, the mean of the ranks is provided)
p_values: p values from the Pearson’s correlation scores
p_adj: p values adjusted according to the Benjamini & Hochberg (BH) method
