## Status

Not built yet.

arcform does not do this yet. [Its place on the roadmap](https://meridian.online/roadmap#run-a-hypothesis-test)

## Variants

- Design and read an A/B test: Choose treatment and control units and measure the change between them.
- Compare several group means: Test whether the means of several groups differ, by ANOVA and related tests.
- [Compare two means](https://meridian.online/operations/run-a-hypothesis-test/compare-two-means): Test whether two means differ, or whether one mean equals a given value, by a t-test.
- Test fit to a distribution: Test whether values follow a given distribution, such as a fitted parametric one or Benford's law.
- Compare nested models: Test whether a reduced model explains the data as well as the full model it is nested in.
- Other hypothesis tests: Collections of further tests, such as rank and survival tests, shipped together.
