Finding Correlated Columns in a DataFrame

In addition to TableReport’s Associations tab, you can compute associations using the column_associations() function, which returns a dataframe containing the associations.

Reported metrics include Cramer’s V statistic and Pearson’s Correlation Coefficient. The result is returned as a dataframe that contains the column name and idx for the left and right table and both associations; results are sorted in descending order by Cramer’s V association.

This can be useful to have access to the information used in the TableReport for later use (e.g., to select which columns to drop).
