The\nball divergence and ball covariance based distribution-free\ntests are implemented to detecting distribution difference and\nassociation in metric spaces .\nFurthermore, several generic non-parametric feature selection\nprocedures based on ball correlation, BCor-SIS and all of its\nvariants, are implemented to tackle the challenge in the\ncontext of ultra high dimensional data. A fast implementation\nfor large-scale multiple K-sample testing with ball divergence\n is supported, which is particularly\nhelpful for genome-wide association study.", "License": "GPL-3",
