The package offers multiple methods to discretize multivariate continuous data using a grid that captures the joint distribution via preserving clusters in original data (Wang, Kumar, and Song 2020). Joint grid discretization is applicable as a data transformation step before using other methods to infer association, function, or causality without assuming a parametric model.
Most available discretization methods process one variable at a time, such as ‘Ckmeans.1d.dp’. As discretizing each variable independently may mis-represent patterns arising from the joint distribution of multiple variables, one may benefit from joint discretization. The methods can handle both unlabeled and labeled data.
