statest
Rust crate for statistical tests.
Now
- T test
- Kolmogorov–Smirnov test
- Chi2 test
is available.
usage
T test
```rust
use statest::ttest::*;
fn main() {
let v: Vec = vec![100.2, 101.5, 98.0, 100.1, 100.9, 99.6, 98.6, 102.1, 101.4, 97.9];
println!("{}", v.ttest1(102.0, 0.05, Side::One(UPLO::Upper))); // true
}
```
Kolmogorov–Smirnov test
```rust
use rand_distr::{StudentT, Distribution};
use statest::ks::*;
use statrs::distribution::{StudentsT, Exponential, Normal};
fn main() {
let t = StudentT::new(1.0).unwrap();
let tvec = (0..1000).map(|| t.sample(&mut rand::threadrng()))
.collect::>();
let tdist = StudentsT::new(0.0, 1.0, 1.0).unwrap();
let ndist = Normal::new(0.0, 1.0).unwrap();
let edist = Exponential::new(1.0).unwrap();
println!("StudentT? {}", tvec.ks1(&tdist, 0.05)); // true
println!("Normal? {}", tvec.ks1(&ndist, 0.05)); // false
println!("Exponential? {}", tvec.ks1(&edist, 0.05)); // false
}
```
