Alex Herbert updated STATISTICS-62: ----------------------------------- Component/s: inference > Port o.a.c.math.stat.inference to a commons-statistics-inference module > ----------------------------------------------------------------------- > > Key: STATISTICS-62 > URL: https://issues.apache.org/jira/browse/STATISTICS-62 > Project: Commons Statistics > Issue Type: New Feature > Components: inference > Affects Versions: 1.0 > Reporter: Alex Herbert > Priority: Major > > The o.a.c.math4.legacy.stat.inference package contains: > > {noformat} > AlternativeHypothesis.java > BinomialTest.java > ChiSquareTest.java > GTest.java > InferenceTestUtils.java > KolmogorovSmirnovTest.java > MannWhitneyUTest.java > OneWayAnova.java > TTest.java > WilcoxonSignedRankTest.java{noformat} > The are few dependencies on other math packages. The notable exceptions are: > > 1. KolmogorovSmirnovTest which requires matrix support. This is for > multiplication of a square matrix to support a matrix power function. This > uses a double matrix and the same code is duplicated for a BigFraction > matrix. Such code can be ported internally to support only the required > functions. It can also drop the defensive copy strategy used by Commons Math > in matrices to allow multiply in-place where appropriate for performance > gains. > 2. OneWayAnova which collates the sum, sum of squares and count using > SummaryStatistics. This can be done using an internal class. It is possible > to call the test method using already computed SummaryStatistics. The method > that does this using the SummaryStatistics as part of the API can be dropped, > or supported using an interface that returns: getSum, getSumOfSquares, getN. > All the inference Test classes have instance methods but no state. The > InferenceTestUtils is a static class that holds references to a singleton for > each class and provides static methods to pass through the underlying > instances. > I suggest changing the test classes to have only static methods and dropping > InferenceTestUtils. > -- This message was sent by Atlassian Jira (v8.20.10#820010)
