# adjustp

# Summary
This is a crate to perform pvalue adjustments for multiple hypothesis tests and is inspired by the R function `p.adjust`. 

There are currently only three methods available: Bonferroni, Benjamini-Hochberg, and Benjamini-Yekutieli.

This crate gives a single interface for each of these multiple hypothesis corrections and does not expect the p-values to be presorted before calculating.

# Usage

The main interface for the tests is through the `adjust` function, which takes a slice of `f64` and a `Procedure`.
If you are using `ndarray` you can use this easily with the `.as_slice()` function.


## Basic Usage
Here's an example for a `Bonferroni` correction.

```rust
use adjustp::{adjust, Procedure};

let pvalues = vec![0.1, 0.2, 0.3, 0.4, 0.1];
let qvalues = adjust(&pvalues, Procedure::Bonferroni);
assert_eq!(qvalues, vec![0.5, 1.0, 1.0, 1.0, 0.5]);
```

And another example for a `BenjaminiHochberg` adjustment.

```rust
use adjustp::{adjust, Procedure};

let pvalues = vec![0.1, 0.2, 0.3, 0.4, 0.1];
let qvalues = adjust(&pvalues, Procedure::BenjaminiHochberg);
assert_eq!(qvalues, vec![0.25, 0.33333333333333337, 0.375, 0.4, 0.25]);
```

And another example for a `BenjaminiYekutieli` adjustment.

```rust
use adjustp::{adjust, Procedure};

let pvalues = vec![0.1, 0.2, 0.3, 0.4, 0.1];
let qvalues = adjust(&pvalues, Procedure::BenjaminiYekutieli);
assert_eq!(qvalues, vec![0.5708333333333333, 0.7611111111111111, 0.8562500, 0.91333333333333333, 0.5708333333333333]);
