# 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
