Struct rand_simple::ReflectedWeibull

pub struct ReflectedWeibull { /* private fields */ }

反射ワイブル分布

使用例

let mut reflected_weibull = rand_simple::ReflectedWeibull::new(1192u32);
assert_eq!(format!("{reflected_weibull}"), "RWeibull(Shape parameter, Location Parameter, Scale parameter) = RWeibull(1, 0, 1)");

// 確率変数のパラメータを変更する場合
let shape: f64 = 2f64;
let location: f64 = 3f64;
let scale: f64 = 1.5f64;
let result: Result<(f64, f64, f64), &str> = reflected_weibull.try_set_params(shape, location, scale);
assert_eq!(format!("{reflected_weibull}"), "RWeibull(Shape parameter, Location Parameter, Scale parameter) = RWeibull(2, 3, 1.5)");
