Implements the estimation of local (and global) association measures: Ducher's Z, pointwise mutual information and normalized pointwise mutual information. The significance of local (and global) association is accessed using p-values estimated by permutations. Finally, using local association subgroup analysis, it identifies if the association between variables is dependent on the value of another variable.
The zebu R package implements different tools related to local association measures in three main functions. It replaces the previous web application written using shiny.
lassie estimates local (and global) association measures: Ducher's Z, pointwise mutual information and normalized pointwise mutual information.
permtest accesses the significance of local (and global) association values using p-values estimated by permutations.
subgroups identifies if the association between variables is dependent on the value of another variable.
