zebu

Description

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, normalized pointwise mutual information and chi-squared residuals.

• 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.
