Stat-Test

This crate provides statistical tests and relevant utilities.


Status

Currently a number of tests are implemented for comparing the means of two independent samples, and for checking assumptions regarding the former tests. However, these tests are all two-sample tests that do not yet support specifying alternative hypotheses.

Comparison of independent means

  • Student's t-test
    stattest::test::StudentsTTest
    Assumptions: normality, homogeneity of variances

  • Welch's t-test
    stattest::test::WelchsTTest
    Assumptions: normality

  • Mann-Whitney U-test/Wilcoxon rank-sum test
    stattest::test::MannWhitneyUTest
    Assumptions:

Comparison of paired observations

  • Student's t-test
    stattest::test::StudentsTTest
    Assumptions: normality, homogeneity of variances

  • Wilcoxon signed rank test
    stattest::test::WilcoxonWTest
    Assumptions:

Assumption tests

  • Levene's test
    stattest::test::LevenesTest
    Tests: homogeneity of variances

  • F-test of equality of variances
    stattest::test::FTest
    Tests: homogeneity of variances

  • Shapiro-Wilk test
    stattest::test::ShapiroWilkTest
    Tests: normality
