Details

The correlate() function provides a convient wrapper around the cor function where the target is the column containing the Y variable. The function is intended to be used with binarize(), which enables creation of the binary correlation analysis, which is the feed data for the plot_correlation_funnel() visualization.

The default method is the Pearson correlation, which is the Correlation Coefficient from L. Duan et al., 2014. This represents the linear relationship between two dichotomous features (binary variables). Learn more about the binary correlation approach in the Vignette covering the Methodology, Key Considerations and FAQs.
