What's New

Distributions

  • Added a CircularContinuous scaffold so circular distributions share SciPy’s frozen API and used it to implement the Kato–Jones distributions (distributions/katojones)
  • All other distributions were also updated correspondingly.
  • Ensured all distriubtions has customized PDF, CDF, PPF, RVS, and Fit implmentation.

Clustering (still WIP)

  • mixture of Kato-Jones (clustering/MoKJ)
  • mixture of seletive, simple circular distributions (clustering/MoCD)

What's Changed

Hypothesis testing

  • overhaul and harmonize the result format of all hypothesis testing functions.

Others

  • many mostly aesthatic changes here and there across many files.
