0.5.1 (2019-07-30)

• BREAKING CHANGE All distributions now expect named rather than positional args
• The normal distribution can now be paramaterised with :location & :scale to align more closely with other distributions
• The categorical distribution now expects a map of {category-name => probability}, rather than separate category and probability vectors

0.5.0 (2019-01-05)

• BREAKING CHANGE Protocol I prefix is replaced with P
• BREAKING CHANGE kixi.stats.core/standard-error-estimate renamed to regression-standard-error
• BREAKING CHANGE kixi.stats.core/standard-error-prediction renamed to regression-prediction-standard-error
• BREAKING CHANGE Tests in the kixi.stats.test namespace, e.g. chi-squared-test, z-test & simple-t-test, as well as those which mirror them in the kixi.stats.core namespace, now return a TestResult. This can be passed to helper functions kixi.stats.test/p-value and kixi.stats.test/significant?
• BREAKING CHANGE Tests in the kixi.stats.test namespace, e.g. chi-squared-test, z-test & simple-t-test, as well as those which mirror them in the kixi.stats.core namespace, no longer accept an optional :tails argument. Instead an equivalent argument is now provided to the helper functions in kixi.stats.test
• New protocols: PInterval for bounded intervals, PDepdendent & PDependentWithSignificance for returning functions of x,PParameterised for returning learned parameters, and PTestResult for returning a hypothesis test result
• Namespace kixi.stats.distribution now contains Student's t distribution
• New namespace kixi.stats.estimate contains functions which accept sum-squares as an argument and return a learned regression model, the standard error and intervals for the estimate and prediction
• Namespace kixi.stats.digest now also contains a sum-squares reducing function
• Distributions now implement clojure.lang.Seqble instead of clojure.lang.ISeq. This means that printing a distribution no longer causes an infinite sequence of draws to be printed

0.4.4 (2018-12-06)

• Baseline release
