# 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
|
|||
|
|
|
|||
|
|

|
|||
|
|
*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`
|
|||
