Ball 1.3.12

• Add a fast K-sample BD test procedure for category variables, especially the GWAS datasets.

Ball 1.3.11

• Update citation information and reference.

Ball 1.3.10

• Add variance (Chi-square) weight for K-sample Ball Divergence test.
• Refine distance computation

Ball 1.3.9

• bcorsis can conveniently analyze category variables (e.g., GWAS datasets).
• Add permutation-free method for the Ball Divergence and Ball Covariance test (both only for constant weight now).
• Add variance (chi-square) weight for Ball Divergence test.
• Fix potential bugs in R version 4.0

Ball 1.3.8

• Improve the reproducibility and efficiency of multi-threading and change the default number of threads as the number of CPUs available.
• Improve the computational efficiency of the KBD test.

Ball 1.3.7

• Modify ambiguous arguments of bcov.test, bd.test, bcorsis
• Modify document

Ball 1.3.6

• Formula interface for bd.test and bcov.test
• Optimize the package dependency

Ball 1.3.5

• Faster implementation of mutual independence test
• Multi-thread support for the test of mutual independence
• Modify document

Ball 1.3.0

• Add a KBD statistic designed for detecting the distribution distinction when a part of group distributions are identical. (setting kbd.type = “maxsum”)
• OPENMP based Multi-thread support for KBD
• Optimized OPENMP parallelism

Ball 1.2.0

• Speed up feature screening.
• Speed up mutual independence test.
• Another K-sample test statistic (setting kbd.type = “max”) is implemented. It is good at detecting the distribution distinction when a part of group distributions are identical.
• Add complete.info component in the output list of bcov.test, bd.test and bcorsis such that user not need to re-run them when user want to obtain the test of result of different statistics.

Ball 1.1.0

• Bug fix
• OPENMP based Multi-thread support for bd.test and bcov.test
• Speed up feature screening for survival data
• Implement Angular metric for compositional data

Ball 1.0.0

• Initial CRAN version
